A Belgian mannequin hand, a candle holder with a talon base, and a “spilled soda sculpture”: these vintage and antique accents are out of the ordinary, and Mantiques — the outrageously unique New York emporium that specializes in art and accents from 1900 to the 1980s — wouldn’t have it any other way. The high-style picks here evoke a more genteel era. Some of our favorites: classic horsebit-detailed silver frames from Gucci, an Hermès pipe rest, and a sterling-silver Cartier shoe horn.
