In addition, he worked for the publishers Quinterno, Abril and Atlantida, as well as the Fleetway group in London. In 1975, he created the series 'El Loco Chavez' with the writer Carlos Trillo in the daily Clarin. The strip was a huge success, and was adapted for TV and published in Spain and France.

He contributed to magazines like Zona 84, Comix Internacional, Cimoc and Play Boy.Already a master of black and white techniques, he devoted himself to stories in color, like 'Ficcionario', 'Tragaperas', 'Merdichensky' and 'Charlie Moon', which were published all over Europe. In 1986, he drew the political fiction 'Chances' in Pilote et Charlie, and received the 'Yellow Kid Award for the Best Illustrator' from the International Comics Salon in Lucca. In the 1990s, he produced several albums published by Toutain ('Charlie Moon'), Les Humanoïdes Associés ('Noëls Fripons', 'Douce Randonnée') and Titanic ('Voyeur').
From 1993, he was present in Co & Co, a new adult monthly of Ediciones B, for which he conceived 'Hot L.A.'. He specialized short erotic stories, which were published in most of the European editions of Playboy magazine. While his main focus in the 1990s were erotic comics, he also produced the family comic 'Familia Tipo' in El Periódico and later in the Argentine daily El Nene Montano. A talented realistic comic artist, Altuna has made many innovations in traditional comic layout, experimenting with the placement of his text balloons.
