Antonio Edo Mosquera, better known as Edgar, was born in Valencia. Edgar did his first artistic work early in his life. During the Civil War, he drew several anti-fascist posters, along with his brother. He joined the publishing house Valenciana in the late 1940s, where his actual career began. Mosquera stayed at this important publisher of infantile productions until 1984, when Valenciana folded. He was active for Jaimito and Pumby magazines. For the latter, he created his most famous work, the Little Red Riding Hood parody 'Caperucita Encarnada'.
