Barnes created detailed terms of operation in an indenture of trust to be honored in perpetuity after his death. These included limiting public admission to two days a week, so the school could use the art collection primarily for student study, and prohibiting the loan of works in the collection, colored reproductions of its works, touring the collection, and presenting touring exhibitions of other art. Matisse is said to have hailed the school as the only sane place in America to view art.
