A backboard accompanying this impression bears an ink inscription by Albert Croquez:
L’unique lithographie d’Ensor/ L’artiste en possédait 3 dont en carton./ il m’a donné celle-ci en 1933. Albert Croquez. (Traces de pliure avec petites déchirures)
[The only lithography by Ensor/ The artist possessed 3 on card/ He gave me this in 1933. Albert Croquez. (Traces of folds with small tears)]
Croquez incorrectly describes this as Ensor's only lithography, as he was at the time unaware of the artist's later attempts in the medium. Lithography, however, does forms a very small part of the artist's graphic oeuvre. Whether his reasons for creating a lithographic version of Le Vengeance de Hop Frog were artistic or commercial, his endeavours were evidently frustrated. Croquez cites only three impressions, including the present example, suggesting that the artist encountered technical difficulties before an edition could be printed. The lithographic version largely corresponds to the first state of the etching, with the subject reversed.
