When researching football’s past, I sometimes come across information that doesn’t catch my attention until I stumble upon something else that connects the dots. That’s the case with a 1955 MacGregor catalog I acquired a few years ago. Since I’ve written several times since then about the evolution of football face masks, I’ve looked at the catalog multiple times. Yet, I didn’t pay attention to the catalog’s distinction between the Marietta, Sowle, and Plastic Bar styles of face masks.
