Brilliant imitation of the style of the great French caricaturist Alfred Grévin. (Cosnefroy we presume was a gifted amateur -- we have no further information on him. N.d., circa 1890. 4to. 31 by 24 cm. 37 original watercolors, all humorist, and superbly capturing the irony and risque spirit of Grévin. We are unaware of any outright copying -- we can not rule that out -- but given that Cosnefroy assiduously, and humbly, asserts "After Grévin", we are of the view that that was precisely what he meant. We do not know anything about Cosnefroy other than his name at this time. We assume that he was an amateur, probably an adolescent, who was gifted and aspired to follow in the footsteps of the famous illustrator. The quality of his illustrations is also not entirely even, and that suggests strongly that he wasn't tracing works he had enjoyed in the humor magazines featuring Grévin's work.
