A 1950s-era Valentines Day card with inscription on back that says, "From Pamela Barner." The small yo-yoing duck image used on this Valentine is identical to the full-size duck image that was used on the Get Well Soon Hallmark card from Hall Brothers, Inc.
Jessie Cheever was the card's designer when she worked for Hall Brothers long ago in Kansas City.
(In 1954, the company name Hall Brothers was changed to Hallmark.)
