Many years ago,under slightly bizarre circumstances, I came across a scrapbook of prints that appear to be by Frank Meadow Sutcliffe. Hardly as renown as Mr. Adams, but a fairly well known and respected British photographer of the late 19th and early 20th C.
Despite a great deal of circumstantial evidence (such as the prints being signed "F.M.S", which was a bit of a hint!) the people who own the Sutcliffe estate were also rather negative, claiming they were not Sutcliffe prints. Later I visited the Bradford museum of Photography, who own a Sutcliffe collection, and they has sequences of certain prints, taken a short time apart. I clearly had 'missing' prints from some of these sequences. It was pretty conclusive, but on reapproaching the custodians of the Sutcliffe estate they were again most uninterested and dismissive. In my case what I have is only of curiosity value, they are only prints, not negatives and of no real financial value, but the knee jerk 'they can't be genuine' reaction did seem very familiar!
