Great Christmas gift for the pop culture historian! My husband remembers seeing 2001: A Space Odyssey in the North Hill Shopping Centre cinema in 1968. After the movie, he used his pocket change to purchase 2 of the "poster-cards" for sale. Sadly, he didn't have enough money to purchase all 4! These have been recently appraised at $50/card, with a set of 4 selling for $375; the asking online price for another set of 4 is currently $1500 US. So, what a deal these cards are: $45/card. These are in great condition; some yellowing on the back of one card. Published in 1968 by Personality Posters, Inc, New York. Each card measures approximately 8 inches/20.5 cm x 5.5 inches/14 cm.
