Kees Sparreboom is a Dutch portrait painter and cartoonist, who later became a comic artist. He began his career at age 15 as a painter of advertisements for movie theaters for the Rotterdam-based atelier of Leo Mineur. It wasn't until after his retiring from his work as a commercial artist that he fully devoted himself to comics. Earlier, he already made a strip called 'Sparreboompjes' for the annual Sparreboom family magazine. To gain a wider audience, he renamed it to 'Puberaaltjes', and got it published by Phoenix Uitgevers in 1999.
His best-known series is 'Boot & Van Dijk', a satirical tribute to the classic 1940s 'Dick Bos' comics by Alfred Mazure. Several books have appeared in pocket format since 2004. He has chronicled his experiences with Leo Mineur in the book 'Rotterdamse bioscoopschilders in de jaren '50' (2002). He has also made comics with a more serious theme, such as 'Roy's Geheim' (2009), about cremation in in commission of the Koninklijke Facultatieve, and 'Mamma Care' (2007), about breast cancer.
