 He also worked as the main penciller for artists Mitacq and William Vance, and made a long promotional comic for Citroën.At the beginning of his career, he was asked by Edgar Pierre Jacobs to help him draw "Blake and Mortimer", but Follet refused because Jacobs did not want Follet's name to be included in the credits.As an illustrator he worked in pencil, acrylic, and other materials, and as a cartoonist was considered a master of the realistic and picturesque drawing style, or as he was dubbed, "the 'most famous unknown' great master of the 9th art".
