Wild West

It is not obvious to make the link between the shown advertising and both series. Indeed, on one side are announced 13 plastic figures and of the other one, only these 12 characters are known.
No other series having for theme Wild West went out to Kellogg, at least for the moment.

These figures are 54mm and plastic flexible. It are made by the famous brand of figure Crescent Toys but are engraved by Kellogg's under the base.
Crescent will also bring out this series but 60mm and often painted.

The Cowboys date 1957 and the Indians of 1958.
