If the photo is as old as you think it might be it would be a good idea to crack it out anyway to replace the backing etc with acid free material to slow down deterioration. A good framer versed in conservation techniques is a photo collector's best friend. I would have them affix the store sticker to the back as part of the photo's provenance.
