Rarest HOF or superstar autograph?

[henson1855]

I have never heard of an Addie Joss autograph coming up for sale,I would love to see one if anyone has a scan.In the past several years I have seen at least three Planks,two from Hunt and one from Heritage that i know of,and two Waddells,one from Hunt and i want to say the other one was on a cabinet card from 1902 but i don't remember who was selling it,i cannot find any info indicating that a Joss autograph has come up for sale at anytime in the past several years,maybe someone else knows?

Addie Joss. There are many known examples of most other 20th century Hall of Famers. There are MANY 19th century stars who were either illterate or there are no known signatures. Likewise, many of the early Cuban and Negro League players were illiterate or there are no known signatures as well of players like Pete Hill and Cristobal Torriente. There are 3 known signatures of Louis Sockalexis known to exist but they are all in Church and University Archives.

Mike Kelly is an exceedingly difficult signature among 19th century players. I would think Hoss Radbourne is near the top of the list too.
