A bold mid-century illustration commands the eye: a double-decked steam ferry — rails packed with passengers in bright period dress — churns through choppy harbor waters, the Statue of Liberty standing sentinel to the left and an art-deco Manhattan skyline surging behind, seagulls wheeling above the smokestack's theatrical black plume. But the real delight is hidden at the card's lower edge, where a concertina accordion strip of sepia miniature photographs unfolds to reveal New York City's greatest hits: the Brooklyn Bridge spanning the East River, Grant's Tomb, Coney Island's crowded beach, Riverside Drive, and more — a pocket-sized Grand Tour of Gotham that any visitor could mail home for the price of a stamp. Published by Progressive Publications, Inc., 145 W. 57th St., New York, NY 19 — placing it squarely in the postwar linen-to-chrome transition era — this unused card retains its full accordion strip in excellent condition, a rare survival given how often the strips were pulled out, played with, and lost.
