This is called a Blinking Eye clock titled TOPSEY, intended to portray a Black Americana ballerina. This is a clock that featured eyes that moved from side to side because they were attached with a wire to the movement of the clock. This piece seems to be missing the eyes, but the photo is dark and I could be wrong there. While the bottom is marked 1858 GERMANY , this does not date the clock which is a reproduction from the 1970 time period. They were recreated in the 1970's and early 1980's by Waterbury and Bradley /Hubbard. This clock has a value of $400 to $500 even though she is a later reproduction.

A similar clock (with eyes) recently sold for 410.00, so I will keep that $400 to $500 range for a value.
