This is an original antique (mid 19th century) engraving from the 7 volume series, "Allgemeine Naturgeschichte, VI. Zoologie" (General Natural History), published by German naturalist, botanist, biologist, and ornithologist Lorenz Oken.
We love the charm of these fish. The detail and color of this print is exquisite. The condition is very good with little foxing and toning around the edges of the piece.
