Title: Colored Thumb Tacks Jigsaw Puzzle
About: Time for a new puzzle. Today we feature a bunch of colored thumb tacks. Thumb tacks or push pins are a short nail or pin used to fasten items to a wall or board for display and intended to be inserted by hand, generally without the assistance of tools. Edwin Moore invented the "push-pin" in 1900. Later, in 1904, German clockmaker Johann Kirsten invented flat-headed thumb tacks.
