In the Pacific Northwest, oysters are still a popular seafood choice; however, even if you shudder to think of eating such a slimy creature you can still create a lovely display of oyster plates from such famous makers as Haviland/Limoges, Wedgwood and Minton. In fact, the collecting of oyster plates seems to be escalating as their use diminishes.
They obviously sell plates, not oysters. But, the plates are really cool.
All photos above from this site, and they generally cost too much to use. The majolica plate below found here. You can find reasonably priced oyster plates for sale on Ebay. And if you're burning to know more about oyster plates you should buy the book.
