Hi everyone, this is my first post. I have been a reader for many years and am finally posting. I am interested in this Margaret Hamilton autographed photo for my collection as she is one of the only Wizard of Oz autos I don’t have to finish a project. It is signed on the front and back with a letter written on back.
Does it look good, I don’t know much about her auto but have compared it to other authenticated examples.

Thanks everyone!
