A rather well known Tangram style puzzle, the Letter T is a classic. At first glance it does not seem possible that the piece will create the "T"; however, if you work the angles you just might get it.
I included this as a party favor/gift selection not only because of the budget friendly price tag, but because it is one of my favorite puzzles regardless of expense. This a puzzle everyone at the party will love solving.
