This is a poster from Langley Associates, from the 70s, before the model went to Gene's desk. I hadn't happened to see this before and thought it was worth posting, in case others also have not seen it before. Interesting topside details. It's also a bit interesting that the photo of Kirk they chose is of him in the EVA suit.
Very cool. Thanks for sharing. I have never seen this poster before. As you say that pic Of Kirk in the EVA suit is indeed a weird choice to put on the poster.
I did some additional digging and found that the poster was one that was offered in the 1976 Langley Associates catalog, as detailed on this page: http://plaidstallions.blogspot.com/2016/08/1976-langley-star-trek-poster-catalog.html?m=1
I did a lot of looking and didn't find another example of that poster, so I bought that one for $12.99. What I was originally looking for was a Scholastic poster from the 70s that duplicated the Lou Feck artwork from The Star Trek Puzzle Manual and from Blish #4. I had one of those posters up for years, back in the day. This was a good compromise.
