This is a Sonic themed 60 piece puzzle by Milton Bradley. It features a nicely shaded jumping Sonic, who is bouncing from a spring, among star bumpers. Rings & clouds are scattered in the background. You can tell this is a pretty early item, as it uses that strange art of Robotnick/Eggman. He's the flattest looking thing among the art (unshaded) and looks out of place in the background (or somehow super tiny) so he seems rather shoe-horned into the art. As you can see, the pieces are pretty big, and the puzzle (seen assembled at left) comes out larger than its box.
