Three Sad Tigers. Author: Triunfo Arciniegas. Illustrator: Juan Manuel Ramírez. Publisher: Panamericana.

Bilingual Book (English/Spanish) Three tigers feel sad because they have lost something of themselves: a mustache, a tail and a fang. But when they encounter a tiger that does not have stripes, they understand that despite their shortcomings, they are still tigers, and that makes them value themselves for who they are.
