First pottery piece

This is the first piece of pottery I ever bought. Back in Louisiana at a student art sale, maybe 1978 to 1979, at LSU, probably spring, when they would have these sales on campus, and people would lay their wares out on blankets. I remember selling some of my pen and ink and watercolors like that. Anyway, this is signed Austin on the bottom, is a porcelain, hefty, big mug. I still use it and it has just a tiny little chip at the front bottom. Likely holds about 16 oz.--for those of us who nurse their tea for several hours, maybe even warming in the microwave when stone cold. I don't know what I would have paid for it, but I am guessing $8 to $10. Pretty nice value for being 30 years old!
