Chicago/St. Louis/Arizona Cardinals
1947 Pro FB Illustrated
vs Lions
From a 1949 Pro Football Illustrated. I'm assuming these are the Chicago Cardinals (vs Eagles).
From a 1957 issue of SI. Chicago Cardinal Ollie Matson wearing a red helmet. I'm not sure if the Cards actually wore this hemet on the field?
1958 Topps Card
The St. Louis Cardinals very first game was at Los Angeles on 9/23/60 against the Rams. For this game only, they wore plain white helmets. For their home opener the following week, they added the familiar Cardinal logo, which has remained ever since.
