1974 Topps Deckle Dating: Fergie Jenkins

Real Rangers hat, or airbrushed Cubs hat?

Topps says it's March 12, 1974. 

Jenkins was traded to the Rangers in October of 1973. Other players involved in off-season moves were airbrushed 1973 photos, with Topps claiming them to be 1974. I believe this is the same. Cubs hats on other cards had that distinctive stitching that is seen here. I don't think this is really March 12, 1974 (a day marked by a Soviet space probe crashing on Mars, and presidential transitions in Guatemala and Venezuela).

I'm guessing this photo was taken at the same time as the hatless image Topps used for this '74 base card.

Also, every photo on Jenkins as a Ranger that I could find online has him with a mustache.
