Debbie Reynolds signals left, riding her Road Master on the MGM backlot during a break filming the 1954 musical, Athena.

Here’s the verso: “Pretty Debbie Reynolds, who appears in M-G-M’s musical ‘Athena,’ is one of Hollywood’s most active young stars both on and off stage. Endowed with lots of youthful pep and vitality, she is energetic about everything she does, inclusing riding a bicycle. But no matter how fast she likes to make the pedals go, she observes cyclers’ safety rules and wisely takes all precautions.

“Hand signals are a must for turning and stopping.”
