Here is a James Cagney autograph that I found in Estes Park, Colorado.  I purchased it in the hopes that I had lucked out in finding a legends signature.  But, of course, like most of the autographs I have I would like to have a second opinion on it.  Is there anyone on here who can help me determine if this is authentic or not?  I wasn't sure if there would be anyone on here who specializes in older actors and actresses.

Real or not?
