The catalogue for the next Native sale in Brussels (info) is online, you can browse it here. A rare find is this beautiful anthropomorphic Pende cup (height: 21 cm; info). It was brought back at the end of the 19th century by Alfred Dewevre (1866-1897), botanist for the Independent state of Congo from 1895 until his premature death, and remained in the family until now.
