Vase with potter's sticker - Helmut Schaffenacker

Hello all,

First time posting here :) I wondered if any experts out there can decode the name on the sticker of this pottery vase?  There's also a maker's engraving of 'V21' in the base.  

The vase measures approx 15cm high and 12cm wide.  Wonderful sculptural shape, I'm guessing from the 1970's?

Sorry about the orientation of the photos!

Any help much appreciated,

Thanks

Helmut Schaffenacker
