By Hilda Amphlett. Richard Sadler, Publisher, 1974.
This is a rather scholarly work on the history of hats covering the past
two thousand years. The arrangement is chronological, by century. If
one's interest is identifying or organizing headdress by country of
origin, this book is particularly useful as the illustrations include
the country where the hat was worn along with the drawing. I am always
impressed when the same author does a book's text and illustrations, as
is the case with this work (see Sibley's bird book if you really want to
be blown away).
