As per ICv2 News:
Dave Sim's "Secret Project" has been revealed -- it is a searing, photo-realistic examination of the Holocaust. Available in May, the 56-page, perfect bound Judenhass (literally "hatred of Jews") was begun in 2005 in response to the 60th anniversary of the liberation of Auschwitz and it will be published this spring during the 60th anniversary of the founding of Israel. Sim plans to keep the volume in print and hopes that retailers will support it as a perennial title.There are some sample pages available for preview on the Judenhass website, but anyone who comes to SPACE this weekend can see 30 original art pieces from the book on display up close and personal.
Sim's visual meditation on the Holocaust has had a profound effect on the industry figures who have seen the entire work. Neil Gaiman's comment was typical: "Judenhass is an astonishing piece of work. Painful and real and unflinching. I don't remember the last comic I read that made me cry, but this did," while Marv Wolfman added: "Judenhass is endlessly disturbing, often unpleasant and incessantly horrifying in its stark coldness. The quotes should never be forgotten or made light of. It is why all people of good will say, 'Never again.'"
Because of the nature of the subject matter, Sim will not advertise or promote this project in the way in which he is marketing his more conventional work such as his new Glamourpuss series. Sim is a longtime supporter of the direct market and the Judenhass Website indicates that the book will "be available exclusively in comic stores."
