Charles Lang Freer's restrictions required that the U.S. collection never be altered, loaned to other exhibitions, or supplemented with outside works, while he later allowed additional acquisitions to the Asian collection.
Notes on verification
Confirmed by Smithsonian's own institutional pages and independent journalism (Hour Detroit), consistent across sources regarding no loans/no additions to American collection and later flexibility for Asian acquisitions. [tier=silver indep_score=0.875 clusters=2 claim_tier=notable]
