Covers approximately 250 sales of Old Masters since 1980, with an average of five listings from each sale. There are 2,700 signature examples of 1,700 artists. Three sections following the main body of this volume offer the researcher easy cross-referencing-monograms and initials, symbols, and alternate names. The appendix includes supplemental signature information on additional artists whose actual signatures were not available, but whose importance could not be omitted.
