Reno Lemaire often do personal illustrations portraying Dreamland characters to his fans when meeting them. Most of the time he asks his fans what characters they want. They are all different from each others and most of them are done on fan's Dreamland volumes. He sometimes does them on clothes, A4 sheets or bags. Those illustrations are rather valuable since they are all unique artwork.
Most of those illustration are done in black and white. But some of them are colored by Salim, his assistant.
