Federal agents have recently recovered dozens of lost historic art pieces ordered and funded by the U.S. government during the Great Depression.

Investigators with the Inspector General’s office of the General Services Administration told the News4 I-Team they located a trove of Works Progress Administration artwork in the attic, basements and storage areas of some California libraries.

The 122 paintings were among an estimated 100,000 pieces of Works Progress Administration that have gone missing in the decades since their completion, according to an I-Team investigation.
