Koberich lists the catalog number of this set as the 30825-25 made in 1967 with a total of 190 cards in the set. This set also as an English-language parallel set that is identical on the front except that the writing on the back is in English....and you can definitely tell it was not translated by an American. Koberich doesn't mention this fact of an English language version so I am going to get a hold of him and ask if he knows anything more about it.
What is really unique about this set, though, is that it contains a trading card of Neil Armstrong....card #185. It shows him with David Scott in their Gemini 8 spacesuits together in front of a satellite dish. Interesting fact is the image is reversed on the card front so this is also an uncorrected error...maybe they corrected it later, which would make it that much cooler. I did an internet search and could only find his 1969 Topps Man on the Moon card as being the earliest trading card known up to this point. Anyone know of an earlier card of Armstrong?
There are some other great cards of other astronauts including Alan Sheppard, Gus Grissom, Ed White, and Roger Chaffee...not to mention the famous Werhner Von Braun on Card #35. I only picked up a partial set so the full set likely has other cards of other famous astronauts.
Cards measure approximately 2 3/4" x 3 3/4"
