Colorful wooden box containing 56 blocks of letters, numbers and math signs. Four rows of 16 blocks each, unfortunately 8 are missing. The blocks are well worn having had much use. Carrying handles on the sides which were added later. The latch is not functioning due to a missing loop. Size: 10" x 10" cubic square. Not sure of the age, but believe the early 20th c. Has a great graphic look.
