Snoopy has always been my favourite Peanuts character — doing his happy dance, or as the WWI Flying Ace on his Sopwith Camel biplane/doghouse. Snoopy began his fantasy career as a fighter pilot in 1965. I always thought his scarf was red (as it is usually shown), but this 2001 stamp has him bedecked in yellow.
And, as a bonus (while researching the colour of his scarf) it seems that during a story line from August 7-10, 1968, for the one and only time, it was revealed to be Snoopy's birthday!
His first appearance was in October 1950, and he would have been about a year old then, so by now would be an astounding 70 — or 490 dog — years old this weekend.
