Raúl Bratesco Serano is a Chilean comic artist, who was a longtime assistant of comic artist Vicar. He was born in Isla de Maipo in Chile's Santiago Metropolitan Region. He was editor, layout designer and cartoonist for the newspaper Clarín from the 1960s to 1973, and was subsequently hired by Pepo to work on the 'Condorito' comic. While working for Pepo, he made his first Disney covers for the Pincel titles Tío Rico and Disneylandia. He also befriended other auhors from Chile, such as Themo Lobos, Alberto Vivanco, Hervi, Pepe Huinca, Julio Berríos, Máximo Carvajal and Oscar Vega.
Undoubtedly inspired by Roba's 'Boule et Bill', he created his own comic 'La Patota', about a group of children and their pet dog Pirata. Bratesco became the assistant of Disney artist Vicar in the early 1980s and has worked on thousands of pages for 'Donald Duck' stories for Gutenberghus/Egmont in Denmark. Vicar's other assistant was Héctor Flores. Bratesco stayed with Vicar's studio until the latter's death in early 2012. He has since then worked directly as a penciller and inker of Disney comics for both Egmont (Denmark) and Sanoma (The Netherlands).
