I am trying to get an opinion about a John Wayne photo personalized and signed dating back to 1952. I had a dealer tell me that it appeared to be genuine and another collector said that he thought that it was secretarial signed. The photo came out of a scrapbook that was complied by Suzanna Lovett done for a 4H project.  Any help from the experts here would be greatly appreciated.

Please explain your reasoning and any identifying markers that you have based your opinion on. I have researched several signatures with a COA and can not determine whether or not it is a genuine signature.
