Roberto Alcázar y Pedrín (originally titled Roberto Alcázar, el intrépido aventurero español) was a Spanish comic strip series created in 1940 by writer and publisher Juan Bautista Puerto, owner of Editorial Valenciana, and artist Eduardo Vañó Pastor. It is the longest-running comic series in Spanish history, with a total of 1,219 issues over thirty-five years, until 1976, and-alongside El Guerrero del Antifaz-one of the most popular and influential Spanish realist comic series of the 1940s. Its early success led its publisher to expand into other titles, making Editorial Valenciana the most important post-war Spanish comics house along with Editorial Bruguera.
