From the same source that produced that great Montanez photo, here are a couple of interesting Cardinals farmhands would very much love to have colorized:
1) Ramon Hernandez had already pitched for the Braves and Cubs before spending 1 1/2 seasons in the Cardinals system. Pittsburgh acquired him before the 1971 season from the Mexican League and he went on to have a nine-year career.
2) Walt "No Neck" Williams appeared in 10 games for the 1964 Colt 45s, but did not return to the majors until 1967 for the White Sox. He spent 2 1/2 seasons in between with the Cardinals, including a tremendous 1966 in which he hit .330 with 193 hits for their AAA club in Tulsa.
3) Jim Hutto was drafted by the Cardinals from the Red Sox in the minor league draft for the 1968 season, but after the year was part of the deal in which St. Louis reacquired fan favorite Bill White from the Phillies. He played for Philly in 1970, the Orioles in 1975.
4) Art Deras was an outfielder for the St. Louis system between 1964-68 without ever getting the call. But his claim to fame came much earlier, as he was arguably one of the best players ever in the Little League World Series. Two years later, he was the standout on a team that won the old Pony League World Series and got a big bonus to sign with the Cardinals. Looks to have been a spring training camp invite for St. Louis in 1968.
