Worst art market in the county!....  Chicago. 

The galleries in Chicago do not advertise in any national art magazine.  That is to say that they do not promote the artist that they are featuring each month in there gallery space.  They do however take a 50% or more commission on any works that do sell.  That is a steep cut into the artist pocket and a steep brokerage fee for someone investing in art.  Going rate for stocks and bonds is 3%.  Makes buying art in Chicago a bad buy.
