Images from a pair of photo albums documenting a group of prazos in Eastern Africa in 1917-1918. According to Wikipedia, a prazo was "a large estate leased to Portuguese colonial settlers and traders in Africa to exploit the continent's resources. Prazos operated like a semi-feudal system and were most commonly found in the Zambezi River Valley." The two volumes contain over 100 photos of workers, houses, livestock, and commercial cultivation and preparation of coprah (coconut meat) and beans, primarily in Mozambique.
