Vintage melancholy monk wooden bookends
You say you already have a pair of rocks to keep your tomes upright. Fine... fine... you can keep them physically upright, but have you considered how they stand morally? For that I'm afraid you'll need a pair of monk bookends. Lucky for you I happen to have the perfect set, which I'm willing to part with... for a modest fee, of course.
These have quite a dark stain, and although they have no cross carved into them, I assure you they are quite virtuous. They're mildly worn from age, and have been outfitted with new felt.
Each is about 8 1/4" tall, 4 1/2" wide, and 4 3/4" deep. The pair weighs about 3 2/5 pounds.
