Shown here is one of the many lots included in the sale, a tin plate automaton featuring a clown an dancer.
From the description of Lot 3174:
Gunthermann, tinplate and clockwork musical automata entitled 'Clown and Dancer', comprising of tinplate clown seated upon drum whilst playing the clarinet, when in motion he nods his head back and forth whilst the opposing female dancer twirls, single fixed key mechanism in working order with 'plink-plunk' type music, later clothing has been applied to both figures
Despite its condition, the piece is estimated to bring from $900 to $1200. Toys were often well-used and many examples were eventually destroyed and discarded. They are therefore often quite rare.
