3D movie viewers, 1952 (NOT a 3D card)
Let’s be clear that the photo is of patrons watching a 3D film–it’s not a 3D postcard, nor was it printed in 1952. Photo was by J.R. Eyerman; the card was mailed from Denver in 1983 with US Olympics 40-cent weightlifting stamp and full postmark. There’s a little postmark transfer on the upper front margin. Grade: 2
