I cannot find a date for this puzzle but most of those I’ve found seem to be from the 1960s and 70s.
I bought this puzzle at a yard sale in a bunch of board games that span 1962-1972, so it makes sense.
Notice the close up pics that show a few minor flaws on the surface of this puzzle. The largest seems to be a fingerprint, found in the upper left corner.
The cut of this sheet is quite challenging! I was impressed with how fun it was to assemble a small puzzle like this. And when I consider its age (which of course I have only an estimate) I’m amazed that this has lasted so long.
Complete as you can plainly see!
