The author of Bambi wrote a pornographic novel. Josephine Mutzenbacher: The Life Story of a Viennese Whore was published anonymously in Vienna in 1906, shortly after Felix Salten moved there. Salten’s authorship has never been proven conclusively, but the consensus of scholars and even the Austrian government supports it.

The book is the fictional memoir of a 50-year-old Viennese prostitute, looking back on her scandalous life. In The Vienna Coffeehouse Wits, Harold B. Segel writes, “For those who knew him it was more in character than Bambi.”

It’s remained in print for more than a century now and sold 3 million copies. A sample in English (NSFW) is here.
