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.
