That’s a closeup of the Surveyor-1 satellite printed above an image of the Gemini orbital capsule, with the words “WE GAVE” (image of Surveyor-1) “a mirror and” (image of Gemini) “the windows.”
The explanation is that Tinsley Laboratories is a pioneer in space science:
The amazing 11,130 pictures transmitted by Surveyor-1, were dependent upon a Brush Beryllium Substrate mirror, optically fabricated by Tinsley …. The optically precise photographic windows for Gemini, were also produced by Tinsley. Tinsley, where engineering and electronic capabilities join over thirty years of precision optical experience.
It’s an ad from the Sep/Oct 1966 issue of Informational Display, when lenses and mirrors could really make a difference in the Space Race.
