This was the cover of "Le Pavé dans la Mare" ("The Cobblestone in the Pond") the magazine of the FFMC (French Federation of Angry Bikers) for the May 1988 issue which contained my article about the Peraves Oekomobil (as it was then called). The title "L'avion sans ailes" means 'The aircraft without wings' and in the cartoon the peage operator is on the phone asking, "Hey boss, what's the rate for aircraft?"
The mag is now called simply 'Moto Magazine'. See for a 2006 story of mine on the annual Quasar gathering, (en francais, evidemment). PNB (from the Blez archives)
