Crowds of Victorian and Edwardian visitors — women in long dark coats, men in top hats — swarm over a vast mountain of ice that has locked frozen Niagara Falls into a winter spectacle unlike anything else in North America: this is the legendary Ice Bridge, a seasonal phenomenon where the Niagara River's mist and spray built towering ice formations that the public was freely permitted to walk upon right up until a fatal collapse in 1912 ended the tradition forever. Published by David Ellis of Buffalo and printed in Germany, this hand-coloured gem captures the last carefree era of public ice-walking, with a souvenir shack at left and daredevils visible near the frozen crest. The postage notice on the reverse — 1 cent domestic, 2 cents foreign — precisely dates this card to the Undivided Back era before March 1, 1907, when the USPS rate changed.
