A campaign to save the Indonesian rainforests: An appeal for donations pointing out that the deforestation of the rainforests not only leads to the disappearance of trees, but that it also leads to the extinction of species like the Orang-Utan, the Sumatran Elephant and the Sumatran Tiger. In that case, millions of years of evolution would disappear into nothing but history. 23 3/8 x 33 1/8, India ink, watercolor and watercolor pencil.
