PHILADELPHIA (AP) — Pharmaceutical giant GlaxoSmithKline has donated a painting with a mysterious past to the Philadelphia Museum of Art.

The work by N.C. Wyeth was one of 16 illustrations made in 1929 for a translation of Homer’s Greek classic “The Odyssey.” Wyeth sold the series to a collector in 1930. The whereabouts of all but six are unknown.

The new building has glass walls and an open floor plan without a lot of places to hang art.
