Yes as Colin and Elizabeth pointed out its the 'Yellow hand' (surely should be arm or almost arm) on the (Rond-Point de Pila ) roundabout here in Chatellerault. Was going around it again on Wednesday evening after a day out in town. Interestingly 'google earth' still shows it with trees - which I much preferred! At first I thought it was showing the evolution of a French model of car - but apparently not, its random manufactures and is meant to represent the industrial aspect (arm perhaps) of the town.
Colin and Elizabeth did a blog on it here... back in March
