These were from the exhibit at the Smithsonian back in 1992. I took pictures just like these when I was there. They had a ton of cool props, costumes and models on display. The restored 11 foot Enterprise was oddly hanging so low from the ceiling, you could actually touch the bottom of it! One prop I really thought was cool was that they had one of the original rubber creatures from “Operation Annihilate”. It looked like it had hardened and was very old looking.
