I don't have anything specific about Brzeska, but I have a small (really
small) book from the San Francisco Museum of Modern Art, published in 1993,
and titled "The Great English Vortex" - it accompanied an exhibition of
drawings from the collection of Mr. and Mrs. Michael W. Wilsey. In it is a
short bibliography on Vorticism. If you are interested in the
bibliography, send me your postal address and I will mail you a copy of the
bibliography. Good luck.
