This puzzle is a fine example of irregular edge-figures as the maker, David Beffa-Negrini, Harrisville, NH has cut all 4 edges into the forms of 16 sea creatures. The result is a stunning puzzle. The maker is the only cutter I know today who uses solid wood (basswood), a throwback to the 1909 era. Puzzle is interlocking, cut partially along color lines with 5 figure pieces in addition to the 16 sea creatures around the edges. Artist: Cynthia Fitting.
