Perhaps these instances of players who didn't necessarily play at the same time indicate that some of these sets might have been multi-year issues? T206 was a set that was produced over a 3-year period, some hobby guides group the various Exhibit sets together (i.e. 1939-'46 Salutations, 1947-'66), why couldn't Holsum or J=K have been issued over a few years' time?
