Query: Disappointing

As an avid inkwell collector I was very excited about a new book coming out on the subject. The last books I got on inkwells were the Badders' books from 1995, so I was ready for an update. Wow, was I disappointed! First, the book is not organized in any way. It seems they may have tried to organize by subject matter (lion, girl, etc.)but this system is erratic. Secondly, they have obviously not taken into account the market fluctuations due to online auctions. I have seen mint inkwells sell for $250 where this book estimates values at $300-$500. On the other hand, I have seen an estimate of a $200 inkwell selling for $400. These examples are not a "one time" situation, they are consistant. I realize that this is probably a difficult factor to add into estimating, but if you are going to call yourself an expert and publish a book about it, you should consider all factors.
