At Christmas time, we all sit down to watch many holiday Christmas specials made by those keepers of the yuletide, Arthur Rankin and Jules Bass. Rudolph the Red-Nosed Reindeer, Santa Claus is Comin’ to Town, Frosty the Snowman, Twas the Night Before Christmas, The Little Drummer Boy and The Year Without a Santa Claus are among the many holiday specials that this duo were behind producing. But Rankin and Bass were not just Christmas-fixated. One of their best and most beautifully constructed stop-motion animation special debuted in 1977, on April 6th.
