I am attempting a life size reproduction of a Taoist cave fresco (china) and in researching colors, came across a genuine Chinese fresco up for auction, from the twelth century. The dealer emailed that it is expected to sell in the $25,000 to $45,000 range, and about five auction sessions ago, a boddhavista head, fragmented sold for $90,000. All in US$

So should I ask $10,000 for my piece:+
