Found an interesting item on Ebay the other day and it arrived yesterday. The Sexton Blake Dossier is a small booklet with tiny little printing that was given to writers working on the Sexton Blake Library series in the 1950s. The series 'bible', basically. It contains brief bios and stats for all the main characters, Blake, his assistant Tinker, his secretary Paula Dane, friends like Splash Kirby, Inspector Coutts, and so forth. It also has descriptions of Blake's rooms in Baker Street, his offices in Berkeley Square, his car, handguns, etc etc. For a collector who is also a writer, this is pretty darn spiffy.
