Note: This series was apparently printed in the United States either by or under license from Fiction House and distributed to Spanish speaking markets in the USA, to Central America, and to Mexico. If it follows the pattern of other titles from the same publisher, production was probably entirely in the United States until about 1958. At that time the actual printing was probably switched to Mexico. So far, very little information has come to light on US produced Spanish language comics of the golden age.
