Before the Sugar Bear we know and love became Sugar Crisp's mascot (the product is now Golden Crisp), Post used three little bears.
Handy, Dandy, & Candy made their debut in 1949, and would appear on Sugar Crisp boxes until 1964, I think, when Linus the Lionhearted, featuring Sugar Bear, premiered on CBS. Handy, Dandy, & Candy would also appear with Roy Rogers and Mighty Mouse, as Post sponsored their shows.
Sugar Crisp was promoted as a "three-way treat", used for breakfast, or as a snack you could eat out of the bowl or the box.
Handy, Dandy, & Candy were retired to make room for Sugar Bear, but don't ya think, since their 70th anniversary is 2 years away, that Post would bring them back??
