I have handled a large number of Norman Rockwell art inlcuding authenticating and brokering sales of his major original works that have sold at auction for record prices. My mentor at Illustration House, ***** *****, who passed recently at age 97, was Rockwell's teaching assistant and I am privileged to have learned from him. Original artwork by Rockwell will continue to increase in value. His actual hand signed prints that were sanctioned by the museum also will remain buoyant on the collector market. Unfortunately, however, mass production, limited runs of plates will likely not see price fervor that they did in the 1980's especially in our lifetimes. The best way to collect, as you stated yourself, is for the aesthetic enjoyment of the objects. Profit zones are simply a secondary bonus.
