What a marvelous idea The Upper East Side has been home to me for many years and, as walking is one of my passions, I thought I knew all there was to know about my neighborhood - until I began thumbing through this fascinating and wonderfully detailed book. Now I want to put on a pair of walking shoes, grab my copy of this delightful new Baedeker, and enjoy Mr. Dolkart's informed prose. I might, for instance, drop by 972 and 973 Fifth Avenue, enjoying, in particular, 972 with its beautifully proportioned bow-fronted residence, one of Stanford White's masterpieces. And then, of course, there is 4 East 88th Street, perhaps New York City's finest Colonial-inspired apartment house with - and this is the kind of detail I so much enjoy in this book - the small carved heads that rise from the arched entrance pediment; one of these is clearly George Washington, peering off into Central Park. My dearly loved neighbors will never be the same again, and I thank Mr. Dolkart and the New York Landmarks Conservancy for this captivating book.
