The Little Red Lighthouse and the Great Gray Bridge by Hildegarde Hoyt Swift, Lynd Ward.
On the Manhattan bank of the Hudson River, a small lighthouse--made of steel and painted bright red--proudly protects boats with his faithful beam. One day a great expanse of gray steel, which also shines a bright light into the fog and darkness, is built over it. The little red lighthouse feels insignificant and useless in comparison but soon learns that small can be mighty!
