Katchor's answer to the question, "How did you find this character, Julius Knipl, Real Estate Photographer?":

"I knew I wanted to do a strip about the city and I knew of this profession: Real Estate Photographer. I didn't really know too much about what it meant except that people take utilitarian photographs of buildings for brokers to use for owners to show. I thought it a strange business because it combines two professions that have all sorts of powerful connotations: real estate and photography and yet it's kind of a pathetic profession, a man that goes around taking utilitarian photographs. It's definitely not art; it has nothing to do with the real estate. There is definitely no interest there so I thought it was a strange position to be in and that's it. He's not really much of a character he's more of an excuse, an observer who passes through a strip. He's a little viewpoint. People always say to me, "Well, you never say anything about him, where he lives or about his family," but I describe everything else, what's in the city, in incredible detail. Everything I haven't described in this city that I've built is this man that I don't really talk about. People sort of fill in the man he must be."
