One piece of ephemera to keep your eye out for is the vintage restaurant menu.
People collect these for a number of reasons. Sentimentality, artwork, and history are a few of the motivating factors that collectors use for buying these items.
I have found numerous menus at estate sales, garage sales, and antique stores. Look in boxes of papers, drawers, old scrapbooks, and sometimes on bookshelves. They often go unnoticed and are usually very inexpensive.
Vintage menus can sell between $10.00-100.00 depending on age and rarity.
