M'mm M'mm Good! These are so much fun to collect! Every year Campbell's comes out with limited edition soup related collectibles. Soup bowls and mugs are the most common, and easiest to find, but there are also salt and pepper shakers, soup toureens, watches, dolls, tins and more. The Campbell's Kids have become a favorite of advertising collectors. They were introduced in 1904 and gradually changed their image to keep up with the times. There are identification and price guides available for the serious collector.
