The Spaceman at Home and at School was a pamphlet for elementary school teacher. It gave them ideas about how to teach about space flight in the classroom with vivid examples. It was not about the history of spaceflight but rather how to build on the "Space Race" excitement already in the classrooms of the time. Probably not too many copies of this one still around.  It is a charming spaceflight craft and costume handbook. I found a copy that come from a retired teacher's classroom. Along with it she had reproduced drawings from the book and a play about spaceflight. She also had mimeographs to hand out of the play and to send home with parents who might have to create a costume.  Miller, Ray. The Spaceman at Home and at School.
