The Hispanic Society Seal has two icons, on the lower half of our seal is a lamb on top of the Book of Revelations, holding the seven seals of The Apocalypse. The lamb symbolizes peace, purity, humble, integrity, and holds a white flag. The flag means "truce", or knowledge to stop fighting. Both, the lamb and the flag, are symbols of "John The Baptist" or San Juan Bautista, the original name given by the Spanish settlers.

The Department of Sanitation's original logo's focal point is the traditional medical symbol, the caduceus, to promote the idea that sanitation can affect the health of the City. The wings, staff and wand were incorporated because the work force, under the commissioner of the time, was called the White Wings and wore white uniforms. Today the yellow caduceus is set on an aqua background with a bright red S in the center.
