The first smurf appeared in "Johan and Peewit" on 23 October 1958 in the album "La Flûte à Six Schtroumpfs" ("The Six Smurfed Flute"). As the smurfs became more popular, Peyo started a studio in the early 1960s. Many talented comic artists started to work. The most notable artists to come from this studio are Walthéry, Wasterlain, Gos, Derib, Degieter, and Desorgher.
