Sorry for the delays in posting, I have been on a short vacation. So today is one of my favorite (and obscure) fictional pop-up books about space. A really beautifully illustrated 1952 book with some amazing text to accompany it, The Jolly Jump-ups Journey Through Space!
Clyne, Geraldine. The Jolly Jump-ups Journey Through Space. Springfield, MA: McLoughlin Bros. (12 p.) 1952.
