Behind the scenes
This one-pager was released on April the 28th, 1938 in Le Journal de Spirou #2 in Belgium. It was reprinted in the Spirou par Rob-Vel collection of all of Rob-Vel's Spirou comics. It has not known an official English printing to this day. The comic, the second-ever featuring Spirou, appears to follow directly from The Birth of Spirou.
