I recently purchased 26 bound volumes of The American Mercury, they came from the University of Virginia Library originally. I was able to use these to verify the articles that were published by Mencken in that periodical. You’ll see this reflected on the Magazines page.
I also recently picked up two paperback editions of Tully, “Circus Parade” and “The Bruiser”.
I hadn’t seen this edition of Circus Parade was published by Continental Books in 1932.
The Bruiser is the Bantam Books paperback, 1946.
