This type of thing upsets me. Yes, the statement regarding this print is true. BUT, what is not shared are the prices obtained following the crash of the financial and art markets.
The one thing to look out for when buying art are are the selective "comps." Of course, most everything sold for more in 2007. Plus, there are the crazy exceptions - on example - Jeff Koons Puppy vase generally sells at auction for about $10,000. During one sale, two people bid one up to over $18,000. These pieces are readily available and come up for auction all of the time. Is the Puppy vase worth $18,000. No, not really.
Dealers are having a harder time finding inventory and selling out of traditional galleries. But, their is a benefit that we can provide - integrity. We will be here and we want you to come back and buy from us again. So, even if one ignores integrity, one should realize that if you cheat a customer or misrepresent, then he or she should simply not buy from you again.
The latest sale of the same print mentioned above was just over $5,000. The asking price is $7,500. The asking price is fair (in my opinion) but the representation of the 2007 price is misleading.
FYI - selective comps are extremely common. I am sometimes surprised when I see such used by what appear to be very reputable art dealers. Artspace, which occupies a large share of the online art market does this too often. I cringe every time I notice it.
