Jaime Tomás was one of the new generation of Spanish artist that began their careers in Pocholo magazine in the 1930s. Other artists of this generation were Cabrero Arnal, Arturo Moreno, Salvador Mestres and Jésus Blasco. His early comics were caricatural, like 'Vida, Dimes y y Diretes del Mago de los Penetes'. He developed a personal realistic style, influenced by Alex Raymond, as can be seen in 'La Isla de los Galeones', 'El Universo en Guerra', 'Fieras en la Ciudad', and 'El Monstruo de Acero'. Jaime Tomás drew also for the Spanish Mickey magazine, like the story 'El Castillo de los Tres Fantasmas' (1936).
