Thanks Michelle, I guess expert may be a stretch for most of us. I've been looking a autographs for a very long time and I'm still just a student. Anyway, it does seem a bit smooth although I've seen a number of these late 1950's signed books and the autographs basically match this one. I do know she did a ton of book signings around the country. She even wrote that she loved doing these signings. According to her, every book she signed was "money in the bank".
I encourage anyone, especially non experts like me, to chime in as well. :0)
