A full set of MMM accessory copies without wheels.
Note: I've seen an example of the card above without an LP trademark on it as well, while another version exists for a US distributor.
6 11/16 in
5 5/8 in
Note: At 79¢ that's a very expensive card, compared to 39¢ for an Apollo Moon Exploring card that had similar contents. And that's a -sale- price too...
Also note the Prospector copy doesn't have a radar dish either.
