"Stolen Car," cover for the program book for Baycon science fiction convention, May 2005.
The version printed on the actual Baycon program book is a little different; this is the "director's cut." This final version is printed for the one and only time in the NEW special, limited Super-Luxury edition of Greetings from Lake Wu from Traife Buffet.
The car is a 1935 Auburn Model 851 Boattail Speedster. The models were Jude Feldman and Alan Beatts, of Borderlands Bookstore in San Francisco. Alan's head was replaced by that of a T. rex.
Here's how the final program book cover looked (notice that they used a slightly older version of the image):
