Behold the mantled guereza (Colobus guereza), aka the guereza, the eastern black-and-white colobus, or the Abyssinian black-and-white colobus, featured here on a vintage tobacco card. Here’s the original caption from the reverse side: “This specimen of the monkey family is remarkable for its solemn facial expression and its beautifully marked fur. It inhabits Abyssinia, the Galla Country and Somali-land. It lives in small troops, in the tallest trees it can find in the neighborhood of running water. It it restless and constantly on the move, but said hot to be noisy like most other members of the same family. It subsists mainly on various kinds of wild fruits, seeds and insects, and spends the whole day in collecting these, retiring to sleep high up in the trees. The Abyssinian soldiers use its fur to cover their shields.”
According to the more contemporary info at Wikipedia, the guereza ranges across much of west-central and east Africa, including Cameroon, Equatorial Guinea, Nigeria, Ethiopia, Kenya, Tanzania, Uganda, and Chad.
