BINGHAMTON, N.Y.- An exciting fine-art discovery a fresh-to-the-market late-1920s oil-on-canvas painting by Taos Art Colony luminary Victor Higgins (1884-1949) will headline Mapes Auctioneers Sept. 30 auction. An old family piece, the 27- by 30-inch artwork depicts a Native American woman in front of an adobe building with a vine-covered column in the foreground. It was purchased directly from the artist approximately 80 years ago and passed through descent to the consignor, who is the original owners great-nephew. The painting has never before appeared at auction or been offered for sale. The Higgins came from a retired gentleman who lives less than a mile from our gallery, said David Mapes, owner of Mapes Auctioneers. He walked into my office one day and said he and his wife were moving
