Piet Jansen was a Dutch comic artist and illustrator, who worked with writer Toon Kortooms in the 1940s and 1950s. Jansen and Kortooms were the authors of the oblong comic book 'Faaske in het land der Peelreuzen', that was published by Oost-Brabant in either 1946 or 1948. Jansen signed this comic "Obé". For the publisher De Spaarnestad, they made the comic strip 'Tom en Bola' for the final three issues of Tombola, the children's supplement of Libelle, in 1954. 'Tom en Bola' was also published in Taptoe under the title 'Billie en Buster' in 1966.
