Magnificent piece of memorabilia was likely exhibited at the fair itself. Stands 42” tall and sits on a base 32x20”. Made of stone (like a cement) and covered in bits and pieces of glass, china, novelty china, and even marbles (actually there is a rare marble on here worth about $300). One of the most creative incantations of the trylon and persiaphere, the perisapehere is a halved circle that opens up. The trylon is removable and shoots to the sky in the modern definition that was this World's Fair. It is electrified and fabulous. An amazing piece worthy of the World of Tomorrow.
