I found these while frittering away my morning browsing through internet auctions (and drinking too much coffee). This was during the golden age of Mickey Mouse & Walt Disney, and a lot of collectibles from this era are quite pricey.
While my mind is on everything wintery, here are a few of Casper's 50s comic books. Casper the Friendly Ghost was created in the 30's and appeared in his first animated short in 1945 (see below). He was a nonconformist ghost who didn't like scaring people, but preferred to befriend them, and his adventures mostly consisted of winning over initially frightened people and animal friends. He was featured in a popular comic book series during the 1950s and 60s and also appeared in several TV series.
