	While in China, Parker met Lam Qua, a Western-trained Chinese painter. Parker commissioned Lam Qua to paint patients at the Canton Hospital with large tumors or other major deformities. Some of the paintings are part of a collection of Lam Qua's work held by the Peter Parker Collection at the Harvey Cushing/John Hay Whitney Medical Library at Yale University. Parker left these portraits to the Pathology Department of the Yale Medical School, which later gave them to the Library.
