This was another painting I did in Advertising Class.  The assignments were very simple.  We had to come up with print ads for common products.  One assignment was to produce an ad for the laundry detergent that we used.  Another was for hot sauce.  This ad was for [WD-40](  At the time, my focus was to do humorous pieces.  However, my technique(this was before computers) was to paint realistically.  This took a long time and the longer it took, the less funny it seemed.

In any case, if you understand movie history, you’ll get the joke.
