Courthouse News Service reports that "a man claims a Scottsdale art dealer sold him a Renoir sketch it claimed was worth $110,000 that was actually worth no more than $6,000."
The Art Market Monitor sums it up as "Man Sues Gallery for Making Fool of Him": it's "yet another art buyer who seems to think the person selling him the art is working in his own interest."
I discussed a similar case here.
