Ok, here's a little baby boomer memory.
7-Up once contracted with Disney to create an animated character to endorse their product. Fresh-Up Freddie made his debut in 1957, with his ad spots meant to air during episodes of Zorro. The seemingly ever-present Paul Frees voiced Freddie, not sure about the other characters in this sports-related ad.
Unfortunately, Freddie was history by the end of the 50's.
