Sunday's Creators
When Sunday was created, a new western was a safe commercial choice. Sales of Lieutenant Blueberry were booming in France,1 Tex Willer was a national icon for Italy,2 and spaghetti-western films were exploding across the globe.3
However, Mora and Fuente also wanted to do something different, resulting in a more adult and complex series than their previous work. Mora reports that he was inspired by Fuente's visuals and challenged to create increasingly better scripts.4
Víctor de la Fuente signed most of his stories and gained worldwide recognition as a result of the series' global distribution. Mora's contribution to Sunday was effectively anonymous, despite his fame as the creator of El Capitán Trueno, Spain's most popular comics hero.
Between 1968 and 1970, Víctor de la Fuente and Víctor Mora completed 12 episodes of Sunday. Fuente then moved out of the comics industry briefly and into advertising, weary of dealing with agents and publishers.5
Mora stayed on as scripter and the final six scripts during 1970 and 1971 were illustrated by the lesser known brother of Víctor de la Fuente, Ramon de la Fuente (1931-1984).6
Ramon is most known for his later lush full-colour adaptations of classic literature such as Robin Hood and Treasure Island.
However, his black and white artwork at this time is similar to Víctor's and their involvement on Sunday is frequently confused. His work on Sunday lacks his brother's holistic and dynamic approach to page composition, but his style provides a looser and cleaner appearance over time. It is possible his early episodes deliberately mimic his brother's work.
