“Vaudeville,” by Caroline Caffin and Marius De Zayas has been listed on EBay. My knowledge of vaudeville is quite slim and for all I know this may be a standard work on the subject, although I have never encountered it before.
What intrigues me is the caricatures throughout the book. There is Bert Williams, above…
And here’s Harry Houdini and Al Jolson.
The copy on EBay is a bit battered and the price is high, with bids starting at $297.95.
Or you can read Google’s scan of the book online for free.
