A humorous drawing by Gris from "L'Assiette au Buerre" of French policeman trying to stop a pilot seated at the controls of a Wright-type biplane from taking off. The caption reads:
"Arrêtez !... Si vous étiez un oiseau, vous pourriez voler... mais comme vous êtes un homme, il vous faut la permissions des autorités compétentes."
[Stop! If you were a bird, you could fly ... but as you are a man, you need the permission of the competent authorities.]
"Les Aéroplanes," issue No. 398 of the French satirical periodical "L'Assiette au Beurre," 14 November 1908, page 541.
