Three rows of men in fancy uniforms. They may be soldiers or musicians but there's no indication. Several very handsome men from the golden age of mustaches. Their sign reads Epernay, 4 Mai, 1911.
On the verso, the card is addressed to Mme. Cros and offers hello to all, signed Paul.
5 1/2" x 3 1/2," satin finish. Fine condition.
