B869.  Nagamitsu Ten by the Sano Museum.  1989.  Softbound, 11 1/2 x 8 1/4″, 171 pages in Japanese.  Nagamitsu was an early master of the Bizen tradition of sword making; many of his blades are National Treasures.  Great black & white (and a few in color) photographs of great swords by Nagamitsu and his followers; the horizontal layout allows for larger photos; quite nice.

Condition is excellent.  2 pounds, 1 ounce.  $145.
