In 1978, Mattel introduced this 9″ action figure of Zeb Machahan from the TV show How the West Was Won. The character Zeb Macahan was played by James Arness.
The box has never been opened, but shows wear and has tape residue from being taped closed. There is also a tear in the cellophane, as shown in the middle photo.
Accessories sealed in the box include a belt, hat, boots, pistol and rifle.
