Carlsbad CA: the institute, 1948. Ring_bound. Card-file reproducing the maestro's personal reference cards, each 5.5x8.5 inches, unpaginated, printed rectos only, the group ring-bound in small but massive specially-titled 6x9.5 inch binder. The item appears unused and unmolested, except for a pencilled ownership on the title card, perhaps a hundred separate entries all told. Binder has collected some dust and a few rust spots, but a very good copy.
