The Phillies and Braves dressed in mid-70s uniforms for an entire three game set from July 26th through the 28th in 2002, although according to Bill Henderson, the Phillies jersey was more accurately depicting the 1987 jersey as it had buttons and not the zipper-front that the Phils wore in that era.
