Unused 4″ x 6-1/2″ card printed in Xograph “depth effect” process, a plastic layering designed to give a 3-D impression, and so it does. Superb addition to any collection of aircraft postcards–really.  Grade: 1

This is a ridged, plastic-covered 3D photo in the size and shape of a postcard but without printing on the reverse, apart from “Made in Japan” and manufacturer’s details. It is meant to be a postcard. Bought in 1980s and never mailed, the front is perfect and the reverse is mottled with age.  Grade: 2

The only thing this 3D card has printed on the back is Made in Japan.  It was not mailed, and though it isn’t marked as a postcard, it was intended to be mailed as one.  Grade: 1

Unused 3D card.  The only thing printed on the back is Made in Japan.  Though not marked as a postcard, it was intended to be mailed as one.  The 3D effect is from the heavy ridged lenticular plastic overlay.  Grade: 1

Two cards are available. They have not been used, but are aging a little on front and back. They’re a little more costly than the other 3D cards because they show actual construction in the city, so they have some historical time value.  Grades: 2

Card bought at Tokyo Disneyland in 1982 and never mailed. It is a 3D-type card in which the motion effect is created by a ridged plastic lenticular printing. Pluto is chasing and then being chased. Front of card is in terrific condition; reverse is mottling and has minor staining. Grade: 2

Let’s be clear that the photo is of patrons watching a 3D film–it’s not a 3D postcard, nor was it printed in 1952.  Photo was by J.R. Eyerman; the card was mailed from Denver in 1983 with US Olympics 40-cent weightlifting stamp and full postmark.  There’s a little postmark transfer on the upper front margin.  Grade: 2

These North Korean postcards are in lenticular printing covered in ridged plastic. On the reverse, in Korean and English, they identify the statue and the location (Pyongyang); they are not formatted in postcard style, though they can be used as postcards and were sold that way.  Two are unused (Grades: 1, $29) and the third was mailed from Malaysia (not North Korea/DPRK!!) in 1991, with two Malaysian stamps and blue Mel Udara label affixed (Grade: 4, $9).

Two of these unused cards are available.  The Landsat-7 fusion image was published by Geocarto International Centre, and the 3D effect (ridged plastic) is realistic.  You can see two airports in here if you know where to look.  Grades: 1

You (and we) already know that these 3D cards made of heavy ridged plastic don’t scan well at all.  But the unused card is perfectly clear.  Grade: 1

This is the outer glossy cardboard cover of a set of six unused, different, genuinely spectacular 3D-effect cards, made of that ridged plastic, and that change their picture as you move them around in your hand.  The scans can’t show this, but as an example, item 20307347B (our next entry) is one of the cards.  The scan shows hands holding grain in a wind farm, but from other perspectives you can see city skylines and a bullet train.  Other cards have cultural, labour, and military themes.  And on top of all of that, each card comes stamped with a mint Y1.20 stamp essentially making these Maximum Cards as well.   Grade: 1

See 37000023A for full description of this set of six cards.

This is indeed a postcard, unused, lenticular printing, rounded corners … but apart from lines to denote where the address should go, there is no other attribution or identification.  We can tell you we got this card from Holland, but it could have come from anywhere.  Grade: 1

Long explanation follows for these amazing cards.  Each set has four 4-1/4″ x 7-3/8″ cards, lenticular printing (3D) on heavy, heavy stock.  Each of the four cards has a food or drink typical of Hong Kong, and each card has a pre-printed stamp corresponding to the picture–like a Maximum Card, but not quite the same.  Hong Kong Post defines these as “Postage Prepaid Picture Card Series No. 48,” with the pre-printed stamp valid for airmail to anywhere.

We have 11 of these sets in total.  All are in their original cellophane wrap.  Five sets have no postmark.  Two sets have the special “Hong Kong GPO” postmark.  Two sets have a special “Philatelic Bureau” postmark.  The other two sets have a special “Hong Kong Delicacies” postmark.  Those without postmarks are US$22 per set.  Those with postmarks are US$26 per set (first day of issue).  Feel free to ask for more details, though we’re not sure what else we can say.  All are Grade: 1.

Unused card, lenticular printing.  We think this shows the interior of a mosque; if not, would you kindly let us know?  The original price sticker is still on the back.  Grade: 2

This 3D postcard has something for (almost) everyone.  Apart from being 3D–lenticular printing–a portion of the back could be pulled out so the card could stand alone on a table, as a framed picture might.  Mailed in 2012 with a coloured meter stamp, light blue trilingual airmail sticker, and one other small sticker affixed.  If not for the extra sticker, Grade 1, but because of that only, Grade: 3

Very nice 3D card (lenticular printing) showing a range of photos of lions and tigers, depending on your perspective.  Two are available.  One was mailed from Spain in 2012 with two stamps (three, if you count the se-tenant large stub of one of them) (Grade: 1, $5).  The other was mailed in 2013, with three stamps and full postmark (Grade: 1, $6).

Internet card with lenticular printing, made in Germany but mailed from Netherlands in 2013 with stamp and postmark.  The motion effect is of the plane flying right at you.  Grade: 1

Our first instinct was to say “cat” but it could as easily be a rat, so we are playing it safe.  The grooved lenticular motion effect causes the drawing to change from just a TV with static, to a clear picture of the animal on the screen.  But we can’t control what the scan finally shows!  Two of these cards are available.  One was mailed from The Netherlands in 2013, with stamp, clear postmark, and Priority label (Grade: 1, $4) and the other also in 2013 but with four stamps and indistinct postmark (Grade: 1, $4).

Heavy, lenticular-printing 3D card but mailed from the United Arab Emirates (not South Africa!) in 2013 with two stamps and very faint postmark.  Grade: 4
