Ironic to me because I've had a tie to the sign business running in my blood for over 40 years. My Grandfather started hand painting signs in Chicago for grocery stores, taught his son the trade, passed it on to his son-in-law (my dad), and now I work part time with my father. It's refreshing to see something like this coming from a sign painter, no offense to the family, but for the most part signs tend to be pretty utilitarian and often customers don't understand or accept design principles, making it pretty hard to incorporate good design. Also it's not usually worth your time. Alright my tangent is over.
