For as long as I could remember, I have been going to Tree Towns Reprographics in Elmhurst, IL for my art prints. They are by far the best print shop around here for artists using inks, watercolors, colored pencils, well....really any medium.
This is long overdue, but I thought i'd give a little shout out!
So if you are an artist looking for a place to make inexpensive prints (under $3 a print), I highly recommend contacting Tree Towns at (630) 832 - 0209. They have consistently phenomenal service, and they are very prompt in reproducing your work.
