- 20 Artifacts
In 2015, The Henry Ford received a grant from the Institute of Museum and Library Services (IMLS) to digitize a selection of artifacts related to electric power generation and distribution. Many hidden stories came to light as staff cataloged, photographed, and conserved these objects. This expert set (the second in the series) presents just another small sampling of those artifacts and their stories preserved by The Henry Ford.
