For my mother-in-law I made a fairybook in 2001 with their grandchildren, our nieces. They were so cute it was fun to build some aquarel-painted pictures with little stories around them.
In 2008 Pegasus Press released the book Malleus Monstrorum 2nd Edition, a monsters compendium for Cthulhu role playing game. There are several works I did combining pencil drawings, ink drawings, photomanipulations and digital drawings. The images had to look like they were actually real findings of Cthulhu monsters in historic books, on ancient plates etc. The book is really worth a look, though it is only available in german language.
