This year is the 50th anniversary of the debut of an animated television special called “Rudolph the Red-Nosed Reindeer,” which became so popular that it is still broadcast each year. The stop-motion animation technique, called “Animagic,” may seem primitive by today’s computer standards, but Burl Ives’ narration and singing endure. The art for each stamp is a still frame from the animated special Rudolph, Santa, and the Abominable Snowman star on stamps of their own, while a fourth stamp features Hermey the elf, touching Rudolph’s red nose.
