When I saw the thread with the pic from a couple of years ago, it triggered something I'd read in my mother-in-law's notes about her life in New
York City in the 1920-30s. Just after her account of seeing Lucky Lindy when his parade came to Prospect Park, she mentions a trip to Niagara Falls
when they were frozen. I still have a few boxes of her stuff to sort through so I'm hoping for photos of that trip to surface!
