This exquisite mask by Abdul Aziz Mohamadu represents a bride. Gleaming brass, aluminum and colorful beads adorn the handsome piece. "Such masks are used during wedding ceremonies by the Bemba tribes from Zambia," he explains. "The mask is presented to a young woman along with gifts for her family. When she is presented to the bridegroom's family, she puts on this mask to show that her family accepts her future husband."
