Minohsayaki: Painted Robes - opening October 4, 2025
ISM-Springfield

Minohsayaki ‘Painted Robes’ presents the story of collaborative efforts by the Peewaaliaki (Peoria Tribe) and Myaamiaki (Miami Tribe), along with non-Native scholars, to reconnect with their historic practice of hide painting. This exhibition was first exhibited at the Richard and Carole Cocks Art Museum (RCCAM) at Miami University in Spring 2024 and is augmented with artifacts from the ISM’s Anthropology Collection that originate from historic Peoria villages. The exhibition is part of the Reclaiming Stories project.
