Trying to post only images that serve a broad need. Here are a couple of managers (one an interim) that have eluded men with Kodaks.
Bill Adair, who coached for many teams, managed the 1970 White Sox for 10 games. No color has been forthcoming. They still wore the blue-based uniforms.
Haywood Sullivan was the principal manager for the 1965 Athletics. Player photos are abundant, but A's woren different uniforms than when he played. Had trouble even finding this B&W shot! Betting someone has something better, to which I would gladly defer.
