Query: Selling snow at Christmas

Although I haven't read the book, it seems that one can attain its flavor by examining the content displayed above at top of page. All the information presented can easily be gleaned from the internet and one wonders how complete the book can be if it has lopped off significant galleries, as per its index, such as Gogosian and Louis Meisel Galleries, among others. Perhaps the author has no real familiarity with the galleries listed, or so it seems.
