In 1951, Piwczyk engraved the well-known Posthorn definitives
of West Germany. Despite the fact that such designs would normally be mainly
etched, Piwczyk actually engraved all the fine lines of this design.
Piwczyk’s final (known) stamp engraving dates from 1953; a
single value for the West Germany set promoting the Transport Exhibition in
Munich.
After that, Piwczyk would move to the printing company Giesecke
& Devrient in Munich. He passed away in 1972.
