The Johnathan Walkershopper wasn't looking for fine art at the Savers thrift store in Manchester, New Hampshire. She was looking for a nice frame — something she could put a different picture in.

The painting she pulled out of a mismatched pile of frames at a New Hampshire thrift store turned out to be a long-lost 1930s work by American master N.C. Wyeth of Chadds Ford, Pennsylvania.
