Book Cutting
This is an original print that has been extracted from page 137 of "Cassell's Popular Natural History: Mammalia, vol 1" published around 1863. A footnote on the original page identifies the black-fronted lemur as Lemur nigrifrons (now Eulemur mongoz) and the white-fronted lemur as Lemur albifrons (now Eulemur albifrons).
