Grand Duke Ernst of Hesse-Darmstadt appears to have been an Art Nouveau/Jugendstil art lover as he set up an artist’s colony in Hesse-Darmstadt and this portfolio must have been part of that. He was the brother of the last Russian tsarina the Empress Alexandra. His mother was a daughter of Queen Victoria which explains the London connection. I blogged a few of these images a number of years ago in a different post. I’m not sure of when I happened upon the Internet Archive but at the time of my earlier post there was no scanned version of the entire portfolio or at least not one I was aware of. This has all the designs.
