Description:  The oil on canvas painting measures 265 cm by 196 cm. In the painting the Madonna, holding Christ Child and flanked by Saint Sixtus and Saint Barbara, stands on clouds before dozens of obscured putti, while two distinctive winged putti rest on their elbows beneath her. A prominent element within the painting, the winged angels beneath Mary are famous in their own right. The angels of this nature are known as putti, and are commonly conflated with cherubim. As early as 1913 Gustav Kobbé declared that "no cherub or group of cherubs is so famous as the two that lean on the altar top indicated at the very bottom of the picture." Heavily marketed, they have been featured in stamps, postcards, T-shirts, socks, and wrapping paper.
