Great Fifty Puzzle
Craig Biscuit Co., Fort Wayne, Indiana, unknown age.
(cardboard box 4" by 4" by 1/2" and 16 wood pieces)
Make a magic square where all rows, columns, and diagonals add to 50.
This is in a theme similar to many versions of the
puzzle that include a 16th square
so that one can make a magic square based on summing to 34.
