"The Executive Committee of the American Red Cross has just officially approved the design for the 1914 Red Cross Christmas Seal, shown in the accompanying picture. Here you see the reproduction of the little stamp, which will be sold throughout the United States during the coming Christmas season to help in the unrelenting campaign which is being waged in this country against the white plague [tuberculosis]… The 1914 stamp is brightly colored with red and green predominating. It is taken up almost entirely by the laughing, ruddy, applecheeked face of Santa Claus. The background in vivid green represents part of a Christmas tree. Instead of the oblong design as used during the 1913 Christmas season, the 1914 stamp is square-practically the size of an ordinary postage stamp."
From The American Red Cross Magazine, July 1914

"It was interesting to note that the purity of the conventional design appealed more to the artist than to the popular fancy. The public likes better the seal which arouses its imagination by the face of the merry Santa Claus, or the laden boughs of a Christmas tree. The earlier stamp designs were composed of a red cross surrounded by holly in conventional form. But the seals of the last few years have depended upon the benevolent face or form of Santa Claus to enhance their popularity."
