[3][4] He is also the undiscovered author of one of the most famous posters of May 1968 events in France showing a threatening CRS brandishing a truncheon.
[6] Among these imaginary objects are, for instance, a "Kangaroo gun" whose "barrel is extensively studied ... to give the bullet a sinusoidal trajectory which follows the animal in its leaps", or a disposable "Plaster anvil ... (sold by the dozen) to be discarded after use, allowing you to make substantial savings."
Jacques Carelman had some of the objects of this catalog created and exhibited (from November 1974 to January 1975) in La Vieille Charité, Marseille.
[4][8] He designed in 1972 a catalog of unfindable postage-stamps ("Catalogue de timbres-poste introuvables").,[3][9][10] portraying for instance la Semeuse, the sowing woman which symbolizes France on coins and stamps, swinging a tennis racket in her majestic gesture, or Papa Doc, the dictator of Haiti, as Père Ubu.
In recognition of the role played in the rebuilding of the OuPeinPo in 1980, Carelman bore the title of Régent of the Collège de Pataphysique, and was in charge of the chair of "Hélicologie", which purpose is to study the Gidouille, i.e. Père Ubu's belly, which is decorated with a spiral.
