Brecheen was a player-coach for the Browns in 1953, and the Orioles' first pitching coach, serving until 1967. These pictures appear to be from 1964-1966 (1964-65 home uniform, possibly still worn at Spring Training in '66) and are an improvement on the baseball card image of Brecheen in the Coaches' Pack.
Well, except for the hideously-bad color in the second picture, of course. The final image is my attempt to improve it, but I'm sure others could improve on my improvements.
