i don't see why not. Artistic talent (of which I have very little but am trying to broaden) is as valuable as writing talent.(which I'm using every day in one form or another.) People have books on the shelves (guilty) and art on the walls. while i can't really see a wife, or roommate vouching for a drawing of a 'Monster" on the living room, a catalog would be a nice place to start. Perhaps with some "Wanted preferably dead" posters of some really bad ones. (though I have reservations about that. Picture a mama monster telling her little ones "you keep that up and the Knights will get you!") [ Just the ones from River Bend City talking more about that later ]
A monster catalog? good idea. you'd need a detailed description of it, habits, likes, dislikes, range age, size. beside the usual pictures.
