People of Hispanic heritage are now the fastest growing ethnic group in the United States. Since the early decades of its founding in the 19th century, the American Red Cross has depended on the help, generosity and leadership of the Latino community.

Here are selections from a series of posters commissioned by the American Red Cross during World War I. These posters honored the commitment communities from different Latin American countries made and inspired them to participate in the humanitarian work of the organization during the war.

Elements from this poster series were taken from other popular Red Cross illustrations from World War I. The nurse with the outstretched hands comes from Harrison Fisher's Christmas Roll Call poster of 1918. The bottom illustration was adapted from Alonzo Foringer's 1918 "Greatest Mother in the World" Roll Call poster.
