Besides being a artist making abstract paintings, Michiel Nagtegaal also makes colourful illustrations and sells them in the Mr. Upside.com webshop as limited edition art prints.

Under the moniker of Mr. Upside, he makes illustrations and doodles. And sells high quality prints of those exclusively online in this webshop. Most of them as limited editions in small runs. Each print is signed, numbered and embossed by hand.
