I had three large boxes full of stuff from Mercury to Skylab. Newspaper front pages,magazine articles, books, promo materials, food packaging labels, cereal boxes, "Science Service" sets, posters, NASA publications, anything I found that was space related.
Unfortunately it was "discarded" when my parents moved while I was away at college.
I guess I got off easy, my sister lost all her original 1959-1963 Barbie doll stuff during the same move. OUCH!
