1581 Abanderada (1950 LA1) is a main belt asteroid discovered on June 15, 1950, by Miguel Itzigsohn^[1] at the La Plata Astronomical Observatory in La Plata, Argentina. This object is named in honor of Argentine first lady Eva Perón, and its name may be translated from Spanish as "woman with a banner" - an appellation frequently used in reference to her as a crusader for social and political change. The asteroids 1569 Evita, 1582 Martir, 1588 Descamisada and 1589 Fanatica were also discovered by Itzigsohn near to the time he first detected Abanderada, and were also given names in tribute to Perón. Measurements by IRAS show the asteroid has a low albedo of 0.05.^[1]
