What happened to Feynman's massage painting?

[Jorpho]

Random thought of the moment:

If you've read "Surely You're Joking, Mr. Feynman", a book of autobiographical anecdotes by a Nobel-winning physicist who has been mentioned in several comics thus far ( http://xkcd.com/397/ , http://xkcd.com/182/ , http://xkcd.com/895/ ). You may recall that Feyman eventually gets involved in producing graphic art, some of which is readily available in one form or another.

He writes at length about a particularly large piece he did for a massage parlor. I was wondering: does anyone know what became of it? Was it disposed of unceremoniously? Is it lurking in a closet somewhere waiting to one day be dramatically rediscovered?
