These books are all incredibly well researched, and gorgeously produced. Many of them are the only books on the given subject and for other subjects they serve as the definitive scholarly text. The ones pictured above are only a small sample of available catalogs.
And while you are there, you must see the wonderful show, Hats: An Anthology by Stephen Jones. There is a catalog for that show as well, but it is not part of the book sale.
there are, of course, many, many amazing hats.
The book sale is at the BGC Gallery, 189 West 86th Street,
near Central Park West, in NYC.
December 8-11 and 15-18, 11 a.m. to 5 p.m.
