ID make Mr. František Vízner, Mrs. Liběna Víznerová was his first wife. This vase is one of two or free pieces, which Mrs. Váznerová designed.
Mr. Vizner said it to Mr. Jindra, he said it to Martina an shee said it to me. We have the same vase in the blue colour. This is my only source, i think, that Marcus Newhall has seen Mr. František Vízner before :-)
Because i often seek here ID, i take for granted write when as is happens and i something know.
