When you are first creating a thing you do a lot of work that never gets seen. I generally use the back of old pages for things like this. The underside of this page is a page from some Zenescope work i did a while's back.
When I drew this I was just trying to get the story tone of the project out of my head and onto paper. Not too cartoony, not too serious. Funny, but not slapstick. Referential, but not ripping someone else off. I want to pay homage to all of the genre fiction I love and shared with my son, the co-creator of Detective History.
