If you spent all day thinking of the unusual items that people collect, we bet you'd never think of hamburgers. Harry Sperl, a German immigrant living in America (where else?), has collected more than one thousand hamburger-related items. including a hamburger waterbed and a hamburger motorcycle. The collection includes more than 500 different hamburgers and some pretty unusual burger material. There are banks, biscuit jars, clocks, hats, trays, erasers, badges, magnets, music boxes, a pencil holder, salt and pepper shakers and, of course, the waterbed, which is complete with a sesame seed covered spread and matching pillows. There are signs, posters, glasses, cups, bowls, stuffed toys, T-shirts, towels, calendars and postcards. Most of the material was picked up at flea markets and garage sales, where Harry trawled for burgers with friend and fellow enthusiast Ron Baynton. When Baynton decided to give up collecting hamburgers, Harry bought his collection and added it to his own.
