Does Anyone Recognize This Rolleiflex Photo

[Deepfins]

I have this great photo of a famous big game fisherman by the name of Dr. Richard Sutton fishing with a Kovalovsky-made fishing reel. The photo was taken in 1937. Has anyone ever seen it before? Any ideas what publication it might have appeared in? If it was ever published, I would like to find a copy of the publication. Anybody recognize the signature? Thank you for any help!! John
