So you've got a photo you're convinced is by L.B. Foote. But it doesn't have his signature, identifying numbers, or stamp (as was described in the first edition of Foote Notes).
If you have the original envelope the photo came in, check to see if there's an invoice or any other documentation.
Foote had different letterhead over the five decades that he was photographing Winnipeg (and invoicing Winnipeggers for same...) and so included with this post is an sample from his Foote & James years and also something mid-career.
Finally, he also sometimes issued a type-written page detailing the photos he took with a ink signature at the bottom, so we're including that here too.
