Does anyone know anything about 'Black Thistle' brand plates?

I just bought 4 plates from goodwill that I like quite a bit and I've been trying to find information on the company to try to find anything else of theirs. It's marked with the brand name "Black Thistle", it says it's made in china and is dishwasher and microwave safe, but they seem likely to be intended to be decorative plates. Does anyone know anything about this brand, or where I could find information on it?? Much appreciated!
