If you're into vintage / retro art, Love Menu Art is going to have a bevy of delights for you. They've taken tons of old school restaurant and diner menus, old illustrations and various banner creeds and printed them in a high quality format for your consumption. I am particularly smitten with The Optimist's Creed:

As you ramble on thru Life, Brother
Whatever be your Goal
Keep Your Eye Upon the Doughnut
And not upon the Hole

It's a silly thing but I like it. You can read more about the history of the motto here and give thanks to Adolph Levitt, a Russian immigrant in the 1930's who made it the driving mental force behind Mayflower Donuts and his invention, the automatic donut making machine.
