Prentbriefkaart aan Philip Zilcken before 1928

This is the back of a postcard sent by artist Charles Paul Gruppé to Philip Zilcken before 1928. It is a handwritten message wishing Zilcken many happy birthdays. The postcard features a New York City postmark from June 1928 and two US stamps. The handwritten message is a testament to Gruppé’s personal connection with Zilcken, and provides insight into his life beyond his artistic practice. Gruppé, a landscape painter and sculptor, was born in Germany but became a naturalized citizen of the United States.
