Ah, Shea Stadium, The Worst Ballpark in the World.

"...Shea...was supposed to be a showcase for the world of tomorrow. You could tell this because it looked breezy, and fun, and half-finished - all bright, garish colors, flimsy new materials and unadorned concrete and pipes and steel cables laid out in that functional, neglected-housing-development style that modern architects used to assure us was the best future we could hope for."

A history here.
