In the 70s we put a lot of cardboard puzzles together. Then a high-flying cousin began sending us one by one by registered mail his collection of wooden puzzles. Some were Par puzzles, designed with the funky sensibility that Par was known for. The most difficult was a reproduction of Christina’s World by Andrew Wyeth. Almost all grass. I thought I would start my own collection until I realized I couldn’t afford to. The expense is not hard to understand. Cutting a puzzle by hand takes skill and time. There must be a way to automate the process.
