Size: Approximately 37 cm wide, 28 cm long, 2 cm deep. This plate was custom-made by an artist about 15 years ago. There is no potter's mark. It turned out larger and more impressive than I expected, and I couldn't bring myself to use it, so I wrapped it in bubble wrap and stored it away. I don't think I'll have a chance to use it anymore, so I'm putting it up for sale. The back looks rough, but it's not actually rough to the touch. The color is not too overpowering, so it should go well with any dish. It would be great for serving food or as a one-plate dish. However, it is heavy, so it might not be easy to use casually. Please read the profile before purchasing.
