Possibly. The "coc" in the surname looks kind of odd but then the "k" looks good. Otherwise, it overall looks pretty good to me. Any backstory on it? Maybe he was distracted as he was finishing it up?
Good prices fade, bad graphs never change. His name is misspelled. You will always see that and it just gets worse over time. If you tried to sell this to me I would immediately say "...he misspelled his own name...?". Who is selling this? Who has opined it genuine? At best it appears uncomfortable, certainly atypical.At worst it may well be a forgery.
