Although mainly a cartoonist, Eddy Ploegaerts (Ploeg) has drawn the pantomime comic 'Prosper' in magazine Tintin. He made his debut at the Salon van de Vlaamse Humor in Antwerp in 1959. His cartoons have appeared in magazines and papers like De Linie, 't Pallieterke, Zondagmorgen, De Post, Humo, Ons Volk and De Standaard. He also designed the 'Even Geduld' ('One Moment Please') intermission cartoons which were broadcast whenever the Belgian TV channel BRT faced technical difficulties. Another cartoonist who created title cards for this function was Buth.
He worked for Lombard's animation studios Belvision from 1964, and during the same period, he made his first illustrations for Tintin. He produced the comics 'Prosper' with Greg and 'Egide' with Hubuc from 1966. Starting in 1974, he made a slapstick cartoon series starring 'Prosper' on his own. He also created the character 'Picazzo' for Ons Volkske.
