More than just block-building fun, this wooden factory set is an eye-catching introduction to graphic design. It's based on the work of House Industries, a hip, graphic design firm that creates lettering inspired by comic books, hand-painted signs and mid-century furniture. Each handmade, basswood block has grooved sides that interlock for easy stacking, while the remaining faces are embossed with a playful array of letters, numbers and symbols. The bold, black-and-white color scheme makes building patterns as much fun as building towers and houses. And when playtime's done, there's no need to box them away: they make a decorative accent that is both playful and sophisticated. Handmade in Grand Rapids, Michigan.
