Wilbert "Bert" Franklin is shown here with the Montgomery Rebels. The photo is from the Montgomery (AL) Avertiser of April 16, 1965.
To my knowledge, Franklin was never on a major league spring roster nor was he a non-roster invitee to a major league spring camp. His Sporting News contract card is at the following link, and it shows him only being transferred among minor league teams, never mentioning a movement to a major league club.
