@bkcunningham, I don’t. In the past I have awarded myself one good long look at the picture before I started, and then put the lid out of sight (actually, it stayed upside down with sorted pieces in it). But now I don’t even do that. I have a general idea of what the picture is because I chose it, but I don’t peek while working on it.
Those Liberty puzzles are great, though, well made and of very nice quality. They are lovely to handle, and the art reproductions almost seem to glow like oil paintings. I love the whimsies (which I also remember from ordinary puzzles when I was a little girl). And if you really, really have to have help, you can actually see a diagram of the complete cut puzzle if you click on the images in the individual item pages.
Back in the 1930s, when there was a mad rage for jigsaw puzzles in the U.S., puzzles did come in boxes with no picture. The surprise of seeing what you had was part of the fun. There were puzzle lending libraries, and some people subscribed to puzzles for regular delivery. Cutting the pieces was a cottage industry, one that was especially popular with women, who cut them on a tabletop jig saw. For many people, picture puzzles provided a glimpse of art works that they weren’t going to see any other way.
