While paging through my '70s Cubs binder, I found this 1977 card...
The White Sox switched to their collared uniforms in 1976, but wore their old unis in spring training. Chances are Otten never wore the new unis.
Wheelock and Willis were both on new expansion teams. All the Blue Jays and Mariners in the set were airbrushed.
The Cubs' Mike Krukow was the only shown in his real hat. No airbrushing was necessary...though getting rid of that bad mustache wouldn't have been a bad thing.
