Walnut from Köhler's Medizinal-Pflanzen / Juglans regia

This poster of the Walnut (Juglans regia) from an old botany book is simply amazing! It is rich in detail and beautifully colored, making it a great addition to any home. Its vibrant greenish colors and brown-yellow walnuts, against the lighter background, certainly create a balance for the eye that sees it. The poster shows the unique structure of the hard, fibrous shell as well as its inner seed, which has provided people with nourishment for centuries. It's a lovely reminder of how nature connects us all through time, even now.
The illustration is a copy of the walnut also known as English walnut or Persian walnut, Latin: Juglans regia, from Köhler's Medizinal Pflanzen, 1887.
