This is one of my favorite comic strips. "Pearls Before Swine" can be found in most newspapers comic section. Strip artist Stephen Pastis created this homage to hopper for the cover of one of his treasury books titled "Nighthogs".
The cover cuts off the whole work. The diner is actually titled "Pearls" but on the cover of the book, all that is visible is the "LS". The biggest version I could find showing the full diner name is still pretty small.
