You mentioned that he signed allot in his lifetime, but what stands out to me is the unrushed eloquent cursive that has been lost with modern times. People took pride with having good penmanship in the fountain pen days that you just don't see anymore. The one thing that I would be concerned with is the "toning" issue you mentioned. The paper that it is attached to may have a ph issue and also the glue that was used could degrade further with time. I'm experienced with archival framing regarding artwork and considering the value of your piece, you may want to limit exposing it to direct light as that could further accelerate the acid burn. Again, really nice autograph.
