One evening I got super enamored with the idea of in-universe paper memorabilia in the Kaoru & Jan universe. I mean, I'm always enamored with the idea of in-universe art and such, I built SOTW's story completely around that idea, but all of these were drawn in that sort of spur of the moment feeling.
I adore stamps!!! The art style they have is so cool and I just love the... concept of them. I collect them as well, though not actively, I just hoard any cool stamps I get or see available for buying. These stamps feature wildlife (in a magical world, all sorts of creatures would just be wildlife, wouldn't they?) along with people famous enough to be on a stamp. In universe, neither Kaoru nor Jan would be famous enough to be on a stamp that young, but that doesn't matter. Ada Hayes, however, is famous enough to be on an anniversary stamp such as that one.
Image description: A bunch of stamps sitting on a white background. The largest stamp is on the left, and has screenprinted red and blue ink on it. A short Japanese person with shoulder length messy hair stands shoulders up on the left side of the stamp. There is a big smile on their face. On the right standing next to them is a taller Norwegian man with short blond hair. He is also smiling. The text on the stamp says "7" and "KAORU AND JAN" and "FOREVER". The next three stamps are small and matching. They all read "MAGICAL WILDLIFE" on the top of them. The first small stamp has black linework and a desaturated green background. Below "MAGICAL WILDLIFE" it reads "QILIN" and "5" and in front of the background is a Qilin roaring. The next stamp has a dark blue background and says and has "JÖRMUNGANDR" and the third stamp has a red background and says and has "PHOENIX." The fifth and final stamp is extra long and is in screenprinted reds and oranges. In the center is a smiling woman with neck length hair. The text around her reads "HAYES ORGANIZATION OF MAGICAL MEDICINE" and "1875 - 1975". END ID
