An early French comic (1888) might have served as an inspiration for a later Adamson gag. The illustration is from a publication in a Flemish illustrated weekly (De Vlaamsche Patriot, 6 September 1891), but as Antoine Sausverd has found out, it was earlier published in a French magazine (La Caricature, in 1888). In that French publication A. Sorel was given as author. It remains a mystery why the Flemish weekly presents us with a different name. Anyhow, this silent comic might have inspired the Swedish artist Oscar Jacobsson for the Adamson gag, originally published in a Swedish weekly, Söndags-Nisse, 4 February 1923.
Both artists succeed in telling the joke by pure visual means, but Sorel's choice to work with silhouettes for his characters is actually not very efficient in showing the impact of splashing afterwards, contrary to Jacobsson: notwithstanding his dirty face, Adamson's facial expression is clearly visible and funny.
