Nick Trost's Card Trick (1978)
This is a card trick made in 1978 (one of the scans is the envelope my card trick came in, postmarked in 1978 with the return address being Nick Trost!). As you can see there were 5 cards that were included, one of them two sided with one side being R2-D2 and the other being C-3PO. A very neat addition to any complete vintage Star Wars card collection.
