The  Galleon  Puzzle

This is a very old Danish puzzle, more jigsaw in nature, made of cardboard triangles (the sides are clipped because it didn't all quite fit on the scanner).  I have 7 of these in various shapes.  They are more difficult than they first appear since basically all of the pieces are the same shape.  It comes with a solution in black and white on a separate piece of thick paper cut to shape.  $10
