Hearty congratulations to Kevin Walsh, webmaster of Forgotten NY, a site devoted to the physical remnants of decades and centuries past in the five boroughs and environs -- old neon, abandoned subway stations, abandoned diners, humpback street signs (think Sesame Street), vanished streets, ghost ads -- and that's just scratching the surface. It's a site you can explore for hours.

Kevin's years of diligent research have spawned a book of the same title. Forgotten New York: Views of a Lost Metropolis, published by Collins, made its debut last month in hardcover and paperback. Kevin has a page devoted to the book's release party, held at a Greenwich Village pub that was once a speakeasy. Naturally, Kevin provides a short history of the bar, its famous customers, and explains how the term "86" is connected to the place.

Time Out New York put the book on its cover, with a feature story and several sidebars. And Kevin's cousin, Tom Paul, posted a web scavenger hunt as a contest. While the contest is long over, the five questions he asks will send you searching through forgotten-ny.com looking for the answers, giving you an overview of the hidden treasures you'll find there.
