I think I've mentioned, PSA/DNA has James Dean exemplars on their AUTOGRAPHFACTS page from The Written Word, Heroes And Legends.... and even a publicity photo that was sent out by his movie studio and apparently "signed" after his death.
I remembered. I was wondering how long this list would be actually. I remember (I think) Ballroom mentioning a Ringo and perhaps a Macca, there is your Dean, the Crawford you showed, another Crawford(!) "To Edwin," several "Gleason" from the "Honeymooners" page (not the Gleason page)...good grief.
