We are pleased to officially announce the donation of the Windows through Time exhibition materials to the National Building Museum in Washington, D.C. and the National Building Arts Center in Sauget, Illinois. The collection, which includes twenty-six historic windows and a number of exhibition-related display and mounting materials, was originally curated to accompany the organization’s inaugural conference in 1986 and has toured various locations throughout the northeast United States over several decades. With this donation, HPEF hopes that there will be a renewed interest in the study and appreciation of historic window production.
