With Love on This Valentine's Day

"A young man has written a note on a photo of himself. It reads, "I love your darling" and is signed, "Bob." Kathryn Beasley had this copy made. No date was noted." -- Library caption, from the John Holly Williams Collection at LLF.

This photo has a timeless quality to it.  I would be curious to learn the date it was taken.  If anyone recognizes this man, please leave a comment here or on Facebook.
