Quote about the tiles in New York Times-
"One of the most effective methods of designating streets that I have seen is that used in New Orleans. It consists of blue tiles four by six inches and three-quarter inch thick on each of which is a five-inch letter of the alphabet in white. . . . These not only present a neat appearance, but are large enough to be read without difficulty. -- Albert E. Davis of the Bronx, N.Y., in a Dec. 3, 1913, in a letter to the editor of The New York Times."
