This lot of four 1910 postcards featuring Naval humor is a rare find. Each 3.5" x 5.5" postcard is printed with a lithograph and signed by different artists.  The postcards were published by F. Clifford and are an original, not a licensed reprint. I think F. Clifford was located at 26 Marlborough Street in Newport Rhode Island.  These rare and unique postcards would be a great addition to any collection.
