Anybody know when this was published, and who drew it? I see what appears to be a strong Warren Tufts influence. I wonder if the dates of this comic and Tufts' Casey Ruggles would make that possible. Of course Tufts was in turn strongly influenced by Alex Raymond and the Raymond influence could be what I see in the Spanish artist's work. Still, many of his faces and inking techniques resemble Tufts more than Raymond. I admit I could be full of hot air. Tufts wasn't an artist who spawned many followers.
