The surface of the shield is painted with delicate foliate scrolls in silver leaf (now tarnished) on a black ground. During its working life, the shield was painted a second time with two shields bearing the arms of the Nuremberg patrician families Ketzel (on a black ground, a silver monkey holding a gold ball) and Igelbrecht (on a silver ground, a black hedgehog with three gold apples stuck on its spine). The arms may have been added in the late fifteenth century by the Ketzel family as a memorial to Heinrich Ketzel the Elder (died 1438), a citizen of Nuremberg by 1435–36, and his wife Anna Igelbrecht, who married in 1391.
