Jo Stafford moved to Columbia Records in 1950. Though the newspaper erroneously called her Doris Day, the song "Ay-Round The Corner" was done by Jo Stafford in 1952. Billboard February 23, 1952, page 43. To be certain that the photo was not under copyright, a search of artwork registrations was done for the years 1950, 1951, and 1952. This covered Jo Stafford's time at Columbia up to the point where the photo was published. There were no results for Columbia Records, Metronome or any photos of Jo Stafford for the mentioned time frame. There's no evidence to suggest that copyright was ever registered for the photo.
