Tom Robbins
In these frame blowups, author Tom Robbins (as "himself") and "Jack" (Vince Balestri) sign each others' books in a ceremony written into an early Beat Angel screenplay draft and filmed at the Northwest Bookfest in Seattle.
Despite the editors' good efforts, the scene did not fit in the new story. Tom's cameo will unfortunately remain on the proverbial cutting room floor (actually it's kept in a can on a cabinet shelf).
