Anyone familiar with these pineapple mugs?

I won these on Ebay (one of 6 actual purchases I have made on Ebay ever) and was wondering if anyone has these or has seen them before?

They appear to be home made or craft, but I don't know for sure. Anyone??

Thanks,

PTD

Those don't look familiar - I assume there aren't any markings on the bottom?

No markings, flat white ceramic. Almost look like a Daga mug finish. These appear to be pretty old, but nothing to indicate if they were commercial or home made.
