His autograph changed a few times -- notably the name with which he signed (John; J. Honus, H., even Hans), as well as the style of certain letters (sometimes his 'W' connected to the 'a', sometimes it didn't; the style of his 'e' changed, etc.).His pre-1920 ones had the most flourishes (I'll try to locate examples).Here are a few examples from 1919-1955 taken from all over the Web:1919:1920:1925:Unknown Year:1936:1939:1955 (this last one realized $14,000 with all the documentation):
