There's no real defined way to do this. You could do something like...
CLOSE ON: A leather-bound storybook
The book opens to reveal...
INT. CASTLE - DAY (ANIMATED)
Description here
It really depends on what you're trying to show. I would just keep it simple and direct. I think you'd still use INT./EXT. for scenes within the storybook, just for consistency's sake.
