"Albrecht Durer was the greatest painter of all time, unrivaled in engraving on copper," says Sofia Frankl, who has been working in Albrecht Duer House in her workshop for 25 years. Anyone who watches Sophia Frankl knows that the artist said: "You can print from 50 to 70 copies on one plate." By the way, Dürer's most famous works, such as a rabbit and hands, were not copper engravings. They were painted. Only Sofia Frankl engraved them on copper.
