If you're ever stuck in a library with nothing to do (or are procrastinating from whatever you are doing), head over to the natural history section, pick out the oldest book you can find, and flip through to all of the animal pictures. They're innocent, demure, and will make you feel like you've just stepped into a pine forest in the 1800s.
Slinkymalinkicat is an online store that sells all sorts of vintage prints, hand coloured woodblock, engravings and a few chromolithographs that give you the same feeling. Oh, and everything is at least a hundred years old! A few of them we've displayed for you here, but to see more, head over to their website.
