Back in 1947, New York’s famed toy store FAO Schwarz instructed children to dial MU8-2205 for a one-on-one chat with Santa Claus himself.
Needless to say, the little girls and boys were overjoyed with the opportunity, and their expressions were priceless. Fortunately, those moments were captured by LIFE photographers and live on today in a series of rare black-and-white photos.
