How about two for you! There are quite a few digital collections of restaurant menus available to browse on the Internet. Here are two of my favorites:
The University of Washington’s University Libraries put together this great Menus Collection that also includes placemats and other graphic material from area restaurants. Designs, foods, and prices all the way back to 1883 are represented, showing a timeline of American history through our eating habits!
The New York Public Library also hosts a digital collection of menus: the Miss Frank E. Buttolph American Menu Collection, 1851-1930. Miss Burton became passionate about collecting menus for their historical significance and, when she passed away in 1924, had amassed over 25,000! This collection terrifically demonstrates how text and visual graphic design can be visually stunning together.
