oh, also, to be clear.  My above post was rife with sarcasm.  Heavy with it, if you will.  Potentially dripping with it. 
Although, I have to say, I do, honestly, have plenty of magazines that not only have articles about the great masters before our times, used to shill wonderfully bad paints and/or other art materials, some even contain advertisements that USE the old masters' work in them! 
The art world is a commercial place.   It sucks, but the barter system went the way of the sabre toothed tiger.
