The details, via art info:
In 1980, while scheming a silver screen pitch, Michael Uslan, the man who bought the rights to “Batman," came across a promotional image of Nicholson’s character from “The Shining” in the New York Post... Uslan painted over the image with whiteout and transformed Nicholson’s furious features into that of the clownish villain.
The sketch is being auctioned off at ComicConnect.com.
The current bid is $2393. The auction goes through December 3rd.
