Like many of us, I'm interested in several areas in the autograph world. Having said that, I've come to find that my particular focus has settled on pre-1960 Hollywood...from the Silent Era on up to the early Method Actors.
I'm interested in hearing from other collectors in this time span of Hollywood material what your thoughts are on signed photographs TTM (through the mail) vs. In-Person autographs. This would particularly concern signed photographs. Album pages were usually In-Person and contracts and legal docs. usually speak for themselves.
What about publicity photos? I would dare to say most we see today on the market were TTM. Some notable exceptions of collections of In-Person signed photos from the 1930's would include those of Stockton Halstead, Saul Goodman & that still not fully identified entertainment reporter "Mush". These three individuals were different from other autograph seekers because, instead of album pages, they presented stars with nice publicity photos to have signed in fountain pen. A rarity at that time.
I would venture to say that most Golden Age of Hollywood signed publicity photos we see were TTM. Does this present an extra challenge in authentication as the possibility of a proxy might be more of a reality? Do publicity photos (probably TTM) warrant a more extensive and thorough examination for authenticity than album pages? (As a side note, I have found that candid photos can usually be considered having less of a chance of a proxy signature),
Grateful in advance for any interest in discussing this.
