This model, designed for the New York Asia Society in 1984, is the Japanese symbol for good luck. The bat is "happy" because the tapering of the ears in the final step causes it to appear to be smiling. The model is intended to be wet-folded from a half a square of paper, colored identically on both sides, but it may also be folded from a single square folded in half diagonally. A10" square produces a 5" model Michael LaFosse has be producing professional quality origami products for over twenty years.
