Lufthansa of course is German but this 2010 card was mailed from Belarus in 2012 with four stamps, two full postmarks, and blue bilingual Prioritaire rubber-stamp mark.  Grade: 3

Totally generic, this seems to be an internet card from Russia.  What it does have is five stamps and two full 2012 postmarks from St. Petersburg.

The caption gives much more information about this U.S. Army aircraft.  The card was mailed in 2012 from USA with five stamps, three Fort Hood postmarks, and postal abrasions scattered around the edges on both sides.  Grade: 3

Mailed in 2012 with two stamps, partly legible postmark, and Priority label.  The designers seem to have gone out of the way to obliterate details from that aircraft.  Grade: 2

Mailed in 2012 with stamp, Priority, and faint postmark.  Grade: 2

Issued by Pan American Airlines, this unused card describes the two different “luxurious” (President) and “low-cost” (Rainbow) services Hong Kong enjoyed.  An iconic card from the jewel in Pan Am’s empire.  Grade: 1

Where to start?  Well, this 4-7/8″ x 6-7/8″ card was mailed from France (not Puerto Rico!) with five stamps (four the same), postmark, and some barcoding.  The front is clean, and the caption–instead of talking about the airport–has a recipe for Banana Daiquiris.  See what we mean?  Grade: 3

An older card, and while we might have thought they would show a Lufthansa flight and not Aerolineas Argentinas, it’s fine with us.  This was mailed in 2012 from Ukraine (not Germany!) with four stamps and Kiev postmark.  Some postal handling is evident, but this is about as international as any postcard can get.  Grade: 3

Mailed in 1964 with 4-cent stamp and mostly legible postmark, and a fully informative caption.  Grade: 1

Card from 2007, mailed in 2012 from Germany with two stamps (one of them a massive aircraft stamp), postmark, and trilingual Priority label.  Grade: 1

Mailed in 2012 with uncancelled stamp, postmark, and Priority label.  Grade: 1

First, have a look at this card, mailed in 1960 with stamp and full postmark.  Then (as we did), go to our favourite website for aircraft registrations and learn that this plane–whose first flight was in 1958–was involved in a crash landing off New York’s La Guardia Airport on 3rd February 1959.  Flight 320 resulted in 65 fatalities out of 73 persons on board.  These are some of the things you learn when you run a postcard website.  Grade: 2

Unused card from the 1970s.  Grade: 1

Mailed in 1940 with stamp and full postmark.  A small bit of the lower right corner is missing.  Grade: 4

Mailed from Netherlands in 2012, with stamp and postmark.  Grade: 2

Two of these cards are available, both mailed from Belarus (not Austria) in 2012.  One has three stamps and illegible postmark (Grade: 1, $3) and the other has one “M” stamp, mostly readable postmark, and blue Par Avion chop (Grade: 2, $2).

Our favourite web sources for information about aircraft registration numbers lead to at least three different types of aircraft for this number, but it seems certain the aircraft you see was parked by a highway in Netherlands and broken up sometime around 1976.  The postcard is newer; it shows the plane in 1967, but was mailed in 2012 from Czech Republic with stamp, Prioritaire label, and two clear postmarks.  Grade: 2 

This postcard seems to be “motif 3 of 5” from a “2007 limited edition” of other cards.  In any case, it was mailed from the USA in 2008 with a 26-cent stamp and South Carolina postmark.  Barcoding and a slight stain on the reverse.  Grade: 3

Nice card of a genuinely unusual location.  This was mailed in 2012, with three stamps but illegible postmark, as many are these days.  Grade: 1

At last, we have a card from Iceland, and what a card it is.  Great condition, with A Prioritaire label, postmark, and a textured stamp printed with ashes from the Eyjafjallajökull glacier.  Grade: 1
