John Castagno's Artists' Signatures and Monograms have become the standard reference source for galleries, museums, libraries, and collectors around the world. Artists' Monograms and Indiscernible Signatures III: An International Directory contains more than 1,250 signatures of some 1,225 artists. In addition to the standard signature entries, the book features sections for monograms and initials, common surname signatures, alternative surname signatures, symbols, and Cyrillic Signatures. It provides the researcher a reference tool not duplicated elsewhere-one that will save many hours of research.
