I'm always on the hunt for older parquetry puzzles like this, so lovely, but they are hard to find. This is just a little one, German, c. 1920s or so, but it's in perfect shape, in the original box, with tri-fold booklet showing a variety of designs to be made with the tiles. I do sometimes think I should devote myself entirely to searching for beautiful blocks and related objects of creative play--so many good things rolled up into them.
3 1/16" x 7/16" and in excellent condition. C. 1920s I believe.
