Notes:
This is the first issue based on material from Selecciones Ilustrades. The syndicated approach used for distribution of these stories means that reprint sources point to the earliest known printings. An earlier undocumented printing might exist.
Notes:
The German reprint source might not be correct, as a different artist is listed. However the German title matches this story's contents and both appear to be the first episode. This Australian reprint has a clear signature.
