These are picture books purchased when I took the Gakken Petit Pas (0-2 year old class). They also include instructions on how to talk to the child. Set of 3 books. They were stored without being read much. There is green coloring on the cover of "Matte Matte Gy!", (third image), but the inside is clean with no stains or writing. - Dare no Kao? (Whose Face?) - Komoriuta (Lullaby) - Matte Matte Gy! (Wait Wait, Hug!) - Publisher: Gakken Ku-chan Picture Books
