Frossard, Ed. NUMISMATIC AUCTION CATALOGUES. Four catalogues, dated: March 30, 1889; May 16, 1889; June 2, 1891; and October 16, 1891. All 8vo, original printed paper covers. Last with detached covers. Generally very good. Adams 91-92 and 107-108. Frossard's catalogues from this period are generally scarcer. The highly acidic paper covers used by the printer may be partly to blame for this.
