Several sets in the 1920's.

Interesting to see the E-Unc Orange Border set mentioned in discussion of this piece as that is the set that seems most similar in design: colorized photos, last names hand-lettered at bottom rather large, no team designation though, like the Orange Borders, a team name or insignia is visible in most images (only Leach, Laporte, Miller and Steinfeldt in the Orange Borders don't have a team identifier in some way), star-studded array of players including some non-entities. I could easily see this as a mockup for a candy box set c. 1912-3.
