Anyone knows an old comic strip with some creatures similar to the grimlings. The copy i read in the 80ies was probably a French one so it could probably be made by a French artist, but i barely remeber so.... anyway the story takes place in a dark forest. A boy and a girl lost in the forest are caught and then hanged upside down naked by these creatures. The last page features a realistic looking fossilized grimling in a glass vessel as proof that these creatures actually exist!
Any ideas????
