First, let’s provide the English version of bilingual captions on the reverse:  “Hong Kong Post Office Hologram Postcard Series No. (3 through 8, each card a different number) to commemorate HONG KONG ’97 Stamp Exhibition from 12 to 16 February 1997”.  Note that the holographic stamp on the lower left is printed into the card, not attached.  The same is true for the three other stamps on the right, and pre-printed actual postage on the reverse.

We have two sets available.  One has no special postmarks on the reverse; the other (see scan) does.  The scan shows you three of the six cards in each set; the others include a highway interchange, bamboo scaffolding, and a ceremonial dragon.  The set without postmarks is Grade: 1 ($22).  One of the holographic stamps on one of the cards from the other set has a flaw, so the whole set is  Grade: 3 ($10).  Any questions?  Please ask us.  Unused, and with original cellowrap.
