Okay, thanks. I was confused because the OP introduced the first piece (with Johnson's name) as signed by Hazel. I also had not seen any Walter Johnson signatures that looked anything like that one, including the one posted by Packs in another thread, from 1908 (see below).
That 'W' just looks way too different from the following to be Walter Johnson's. Comparing the postcard writing to a 2-page letter I have from the '30s, I just don't see any handwriting changes that are that significant.
