These front and back booklets flip up at the waist to show a small booklet with black and white line drawings and story describing each country. Turn the booklet around and you get a different doll and story. Art and story by Barby and Glen Peterson, for the United States Committee for Unicef.
Juliana and Kwesi are the sides of one booklet, the others: Casimir and Nadia; Shalu and Olav; and Floridor and Hanako. I don't know how many are in this series, but it is very well done.
