Sergio Mulko (born June 3, 1946 in General Roca, RĂo Negro, died June 14, 2014) was an Argentine comic artist.
At a young age, he moved to Mar del Plata, from where he began publishing for the Columba Publishing house of Buenos Aires.
He alternated the drawing of Nippur de Lagash with his creator, Lucho Olivera.
Around the time of this cooperation was born Mulko's pseudonym Leo Gioser, who would write a series of scripts for Gilgamesh, el inmortal, also created by Olivera.
Mulko is the artist who has drawn more episodes of Nippur; more than 150 in two stages: between 1972 and 1976, and between 1988 and 1994.
For many, he is the one who has given greater graphical quality to the series, after his creator, Olivera.
Also for Columba, he has drawn other series such as The Samurai, Espartaco, etc.
With script of MorahĂn, he made one remembered version of Planet of the Apes.
