Sowerby was taken on as a naturalist for Robert Sterling Clark's Expedition of 1909 which sought specimens from the Yellow River into Shensi and then to Kansu province and made the first map of a little-known area of China.
"The Clark" was created by entrepreneur, soldier, explorer, and prominent art collector Robert Sterling Clark, and his wife, Francine.
Robert Sterling Clark discovered the piece in storage and acquired it in 1942.
