Don Quixote pitcher and mug set

I have a large Don Quixote pitcher and 6 mugs. I'm interested in selling them but I have tried researching them to get an idea of what they are worth and can't find anything like them at all. The only identifying mark is the pitcher has the number P-113 imprinted on the bottom. They are all in good condition. My grandfather purchased them in Spain over 50 years ago.
