Behind the scenes
This one-pager was released in August of 1938 in Le Journal de Spirou #18 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.
Its French title, Spirou Partout, literally translates as Spirou Everywhere, and is a nod to "Spirou, Partout, Toujours" (Spirou, Anywhere, Any time), the tagline of the Journal de Spirou throughout the 1930's and 1940's.
