Albert, this might help you:

There was nothing about this photo to indicate that it was not 1927, including paper stock or image quality, other than having only a more modern stamp. It was also posted here in the forum where I asked if anyone knew the photographer, and in my store where a few forum members sent me comments. Didn't hear anything then, and I still haven't heard anything that would make me believe that Heritage was wrong in their original description of the photo.
Oh, and an ebayer who sent a few very rude emails demanding that I describe the item according to his specifications. Someone named Albert...I guess that was you?
Rhys, thanks for your comments.
