Lon Chaney (as Quasimodo) from The Blue Book of the Screen, 1923
An incredible resource for silent film fans has surfaced, thanks to the hard work of David B. Pearson and Graceann Maciolek, reproducing the images and text from the trade publication The Blue Book of the Screen from 1923. Singular images of many top stars as well as directors, producers and writers can be found here, as well as essays like Cecil B. DeMille's thoughts about What Psychology Has Done to Pictures and Jesse Lasky's fairly banal musings on The Future of Motion Pictures.
The overall publication seems to be similar to my An Autographed Who's Who On The Screen (the source of my When Men Were Men series) but with a bit more depth and a lot more names. Check out this sultry shot of Marie Provost or the luminous Edna Purviance or an unusually "come hither" Harold Lloyd. There's also several behind-the-scenes names you probably +haven't seen pictures of, making this a most valuable guide.
