I read this book when I was around four or five, so it would have been 1969 or 1970. Two sisters were with their dad at Central Park in NYC and he took them to the carousel and to watch the ice skaters. They rode the carousel and the horses. The carousel and the horses became real and they rode them off the carousel and through central park, maybe this is when they rode past the ice skating rink. From my memory it was evening time. I remember the book as being in pinks, yellows and oranges and I think the illustrations may be similar to those of Alice and Martin Provensen. Here’s to hoping someone knows something about this book! I have never forgotten it.
