The red-trimmed uniforms at first were only labeled "ST. LOUIS", on both home and road shirts, later replaced by the familiar interlocking "StL" logo. The word "Cardinals" first appeared on both home and road shirts in 1918. The term went from just being a color to also being a symbol in 1922, with the first incarnation of the two Cardinal birds perched on a bat across the word "Cardinals". (Okkonen)
