罕见的自动玩偶"Bob et sa Grenouille Savante", J.A.F.制造, 约1930年

Depicting a quixotic clown with blue glass eyes, elongated neck, articulated lower lip and oversized shoes, sitting on the back of a white-painted chair while an anthropomorphic frog with a fishing line balances on his left shoe. On stage-form wood base with two short flights of steps and seven-camelectric motor, width 24 ¼ in. (62 cm) x height 44 ½ in. (112 cm) with neck extended, 43 ¼ in. (110 cm) with neck retracted and hat, restored and redressed. – Literature:Bailly, "Automata, the Golden Age", pp. 98, 247. – Bob balances a stack of three balls in his right hand, elevates his right leg until his foot is parallel to his forehead, and then lifts off his hat. Balancing the brim of the hat on his toe, he lowers his leg at the same time as the frog dips his line and moves his mouth as though croaking with surprise at what he has found inside the hat. Bob moves his lower lip, elevates his leg again, and drops the hat neatly back onto his head. The trick is accomplished by the articulated toe of Bob's right shoe and the ingenious design of his telescopic neck, which extends and retracts to accomodate the hat. – Jouets et Automates Français (J.A.F.) succeeded Vichy-Triboulet in1923. The firm specialized in electric automata, occasionally producing larger and more complex models (such as "Bob") from its predecessor's catalogue. – We know of only three other examples of this piece: two clockwork (in private collection) and one electric in the Museu dels Autòmats del Tibidabo. One of the largest and most impressive Vichy-J.A.F. automata, in good working order!
