You’ve definitely seen them: commemorative state plates featuring landmarks and slogans from a particular state. I call them “state plates,” but the official term among collectors is “souvenir state plates.” They’re often displayed in kitchens, and the designs range from kitschy to classy to impossibly bizarre — see below for examples of each. According to CountryHome (in their “What’s Hot Now” feature!), state plates have been around since the 1870s:

Souvenir state plates date back to the 1870s. When travel became more accessible thanks to cars, they became increasingly popular with jet-setting travelers. There are tons of unsigned, flea-market-type plates out there, but keep your eyes open for some big-name manufacturers, including Vernon Kilns, Homer Laughlin, Salem China Company, and even Wedgwood.

In the post below, I (with the able assistance of Sadie Eck, standing in as Mental_Floss State Plate Research Assistant for this post) have collected plates for ALL FIFTY STATES. I’ve picked out some favorites first, then the rest are in alphabetical order. Fun things to do while looking through them: count the states you’ve visited, count the states you’ve lived in, spot the craziest designs.
