Arnhemse Courant, 5 August 1940
Little is known about the artist Koen Hansley, except that he is the author of the newspaper comic 'Piet Arends en zijn wondertelescoop'. It ran in local and regional newspapers like De Gooi en Eemlander, Nieuwsblad van het Noorden, and Arnhemse Courant during the early months of the Second World War. Publication in at least Arnhemse Courant was from 12 June until 9 October 1940. The name Hansley is possibly a pseudonym.
