There is a different earlier Gringo/Ringo story also titled "The Chinaman" by Manuel Medina and Carlos Giménez. Although this is currently the earliest identified printing of this story, it is unlikely that this is the first printing of this story.
"Selecciones Ilustradas - Derechos reservados - España" Auraleón's signature appears to be dated 57, although it might be 67.
The final two pages of the original story have been reduced and merged to shorten this to a four page story.
