I just love little puzzles. I think they’re a nice addition to any desktop and make for a great mental distraction when necessary. This particular one was designed by Charles O. Perry in 1967.
“Made entirely of Plexiglas, the manner in which light bounces off this three-dimensional desktop puzzle gives it a jewel-like appearance. A challenge to take apart and put back together, the puzzle comes in a felt gift bag. Perry is a renowned sculptor whose most prestigious work stands in front of the National Air and Space Museum in Washington, D.C.”
