This particular page is from page of the February 1967 issue of Model Airplane News magazine. It is the first time I can recall seeing this contest by Revell that offered to the winner a "full-size Gemini spacecraft!" In 1967, I was nine years old and was a model rocket lover. Like me, a lot of kids would all have - in the vernacular of the day - "given our right arms" to win a contest like this!
I just did a Google search on this contest and amazingly enough, someone else
recently posted the same question about a year ago and actually has a copy of the report in Boy's Life magazine. It turns out that a 13-year-old kid in Portland, Oregon won it, and the Gemini prototype is now on display at the Oregon Museum of Science and Industry. That is a photo of it to the left. Here is a link to the article (unfortunately, the link is no longer active). There were many iterations of the Gemini capsule, and this one appears to be the Gemini V model. The one that Jerry and I sat in was the shorter Gemini IV model, if I remember correctly.
