Roman marble head of a triton, estimated $80,000-120,000 at Hindman.
The 13in (33cm) bust goes on the block as the lead lot in an Antiquities & Ancient Art sale on December 5.
It is unclear when Brummer acquired the bust, but it has remained in the family some 60 years.
Archaeologists determined this to be the head of a triton, the part man, part fish creatures of mythology.
A pair of more complete tritons are part of the Musei Capitolini in Rome, and their heads and hair greatly resemble the features of this lot that is estimated at $80,000-120,000.
