Yogi Bear Picture Book #1973

In "The Mysterious Intruder," Yogi Bear and Boo Boo stumble into a spooky, fire-scarred corner of Jellystone Park, where they encounter the Groozilys—a bizarre, family-oriented bear clan reminiscent of the era’s popular monster families. Written by Michael Maltese and illustrated by Pete Alvarado, with colors by the Western Publishing Production Shop and letters by Rome Siemen, this 1973 Picture Book offers a delightfully eerie twist on the usual antics, all wrapped in a free, nostalgic package.
