During World War II, Boeing was building bombers, and it was better if potential spy planes flying overhead didn't know where. So the factory camouflaged itself.

Boeing covered its roof by building on top of it a neighborhood that looked like nearby South Park, at slightly smaller-than-life-size scale. The history is an inspiration for SuttonBeresCuller's Mini Mart City

Park, which I wrote about in this week's look at land, art, and artifice.

Promotional photos—with prettylady models!—were released after the war. More pictures of the roof and the factory interior on the jump.
