John Isaiah Pepion is a Plains Indian Graphic artist from the Piikani Band of the Blackfoot Confederacy. He is based out of the Blackfeet reservation in north-central Montana, where the Rocky Mountains meet the plains.
John is best known for his ledger art, an art tradition that developed in Plains tribes as the buffalo hide, they traditionally used for painting became scarce, and they were forced to adapt to making artwork on the ledger paper from accounting books. He comes from a family of artists, and pictographic art has been in his family for hundreds of years.
