A humorous representation, entitled 'La Metamorphose, ou Trait', showing people riding on a cart pulled by lobsters. Two parrots fly above, and a man rides a galloping horse inside a type of treadmill. A head protruding from the body of the cart which is made from a barrel, appears to be blowing air or vomiting into a receptacle below.
