Back in the 70s and 80s, at the beginning of each school year (and occasionally in the middle) I would get a new three-ring binder. These were typically the plain, old-fashioned denim binders. Once I got a Trapper Keeper (bright red) and a few times I got binders with some picture or other (Star Wars, maybe?). Typically, though, it was plain binders full of college ruled paper.
Since I discovered D&D pretty early in my academic career, I would normally swap out some of the ruled paper for graph paper and spend as much time filling my notebooks with maps, characters, and game notes as math problems and essays. When I wasn't working on homework or gaming material, I would draw on the binders. Decorate. Awesomize!
I remember at various times having band names and logos copied from album covers, a D&D logo, TIE fighters, and such. I would painstakingly copy a design just to turn around and cover a bit of it with a random sketch while I was half dozing in math class. The inside was home for stickers and more doodles. Eventually the whole cover, inside and out would be covered with drawings and random stuff.
I know that I wasn't the only one doing this. I saw it every day in classes all day long. Unfortunately, I can't find any of these notebooks online. So I am turning to the hive mind. What did you put on your notebooks back in the day? How did you decorate them? And did you happen to take a picture?
