MONSTER BLOCKS FOR PLAYHOUSES (Aug, 1933)

MONSTER BLOCKS FOR PLAYHOUSES
Youngsters may construct real playhouses and full-size, serviceable pieces of furniture with a set of giant building blocks introduced by a California toy manufacturer. Made of wood, the blocks include cubes and flat rails in a variety of sizes. A clever dovetail interlocking system makes it possible to assemble them securely without nails, screws, or glue. Whenever the fancy strikes the young architects, they can build a different structure.
