I don't know if someone else found about this already, sorry, if it has been posted before, but, a friend of mine, just sent me this this morning, I thought to share it with you.http://unpopperuno.wordpress.com/2014/0 ... olland-dr/
It's in Italian ( I'm Italian) and unfortunately now I don't have the time to translate if from you; basically, the blogger says that after having been trhu some research, he found a little novel published in 1923 from author Jack Whitman on the American magazine Munsey's Magazine ( same magazine that a few months earlier published the novel "Spurs" by Tod Robbins, novel that was the base for the movie "Freaks").
This guys, Jack Withman wrote this novel " The Irony of Fake" which is about the adventures of Sylvia North as a novice in the motion picture metropolis.
He goes on explaining that this girls, a small town girl, goes to Hollywood and, well, the main part of the story, apparently is about some casting about a movie, she meets the character of a cowboy, and there's also a rival girl for getting the part.
I gotta go now!!!
I'll try to do some research myself and, if you know something about it, let me know!
