 Two girls riding a giraffe on a merry-go-round. A difficult puzzle, intricately cut, probably from the 1930s.

  One of Joseph K. Straus's many jigsaw puzzle products. These are reasonably well cut and each puzzle remains assembled on a tray in order to fit into the low profile box. Hard to pin a date on this one, late 1930s to early 1950s.
