Internationally renowned Ernst Hanke
Marion van Nieuwpoort and Poen de Wijs worked with Steindruckerei Ernst Hanke (Ringgenberg, Switzerland). Poen and Marion made the drawings directly on the stone. They were present when the prints were made, decided on the colours and the sequence of the printing sessions. In between printing sessions, the necessary alterations to the stone were made. Ernst Hanke and his assistants prepared the stones, performed various chemical treatments, wetted and dried the paper and operated the press. The printer Ernst Hanke is internationally renowned for the high quality of his prints and above all for his specialization in realistic art.
