Can Anyone Tell Me About this Beautiful Czech Pottery?

Twenty years ago, when I started corresponding with my Czech pen pals, one of them sent me a vase like the one pictured in the second picture below. I fell in love with the beautiful folk pottery! It's Czech, but I have never seen it offered for sale in Prague.

These pictures are on display at Celetna Crystal on Celetna Street. When I asked the salesperson about them she shrugged and said "too old fashioned." Say it ain't so! It's classic folk pottery. So who knows anything about these beautiful things?

Are they Moravian?
