This incredible face to face view of a leopard is the work of German artist Ludwig Fromme. He was born in 1882. His work still sells at auctions, but biographical information on this prolific artist appears non-existent. Adding his name to this postcard seemed like an after thought, too. I dare say Mr. Fromme has not received the proper acclaim due to him. His specialty was painting wild animals, from Wild West bison scenes in the U.S. to safaris in Africa.
I'm going to make a lot of assumptions here just from instinct:
I can't identify the printer by the Star of David symbol verso, but I'm thinking this company tapped into the "I.P.M. of Paris" archives (produced many postcards at the turn of the century) and did these reprints for the Jardin des Plantes (one of seven departments of the Natural History Museum, which includes a zoo in Paris) perhaps to sell as souvenirs in the gift shop. What is interesting is that there is a long rectangle blacking out a block of print and from my lengthy online research, I can tell you that that Printed in Germany is what's blacked out! So, as to when these were reprinted, I'll leave that mystery for you. I'm thinking sometime before WWII, but that is just my guess based on the standard "antique" size of 3.5 by 5.5 inches. That size does verify that it's a vintage postcard and not a modern reproduction.
Here's what I'm sure of: Rich colors! Slightest signs of wear on the edges. No creases. A couple of printing imperfections (red dot and white speck). Looks as if the previous owner tacked this card on the wall using carpenter's putty.
