This one has some famous monsters from movie history at the N. Bates diner (reference to the movie Psycho). It has Frankenstein, Freddy Krueger, Frankensteins bride and a mummy(?). It was done by T. Henseler.
This was a poster advertisement for a Japanese Animation convention back in 2006, using different characters from a few anime cartoons at the diner. The diners name has changed to the "Louisville Free Public Library", where the convention was taking place.
This one is called "Duck Boulevard" and was done by artist Gerd de Kock. It has a bunch of ducks sitting at the diner and what looks to be a duck exposing himself to the ones inside, standing outside with a trench coat opened.
