Onyx (Asterales) Ultra 12-month Day-at-a-time Hardback Dayplanner 2025 (Elastic Band Closure)

Our Onyx design reproduces an 1835 goatskin leather book binding crafted in Amsterdam by Friedrich W.J.C. Kolb. The binding was originally designed to contain a Latin oration on the physiology of plants by the renowned Dutch botanist Willem Hendrik de Vriese. De Vriese, a member of the Royal Dutch Institute of Sciences, Literature and Fine Arts, named many species of plants in the Asterales order (Asterids).
