Things I know: This frame is very old m, circa 1960s. This frame is very cool. This frame is free standing This frame has a small crack noted in the last two photos. Only noticeable when you are looking for it. Things I don’t know: The exact material this frame is made of. The date makes me thing celluloid or Bakelite. Although it very well could be thin plastic. It’s one of life’s greatest mysteries. However, given how old I know it is, I tend to think it’s made from a higher quality than plastic as everything was made of a higher quality back in the old days.
