[GG] Postcards and bookmarks (Patreon)

It has bothered me for a long time that the books didn't have a little extra. I put some postcards in them but it wasn't a thought out system.

So I finally made proper ones. Each book gets a postcard with a different character on it (the one from the cover) and a bookmark with the texture from the cover.

At first I wanted to show items on each bookmark that were important in the book but it seemed too wild. Everything's colorful already so I decided to go with something simple.
