On this print you see 40 technical drawings of traditional joints you see in woodworking. It works as a reference tool if you're handy, but it also makes for nice wall art.
You can find it over on Brighton Exchange for $US33. It's printed on thick stock paper measuring 26x42 inches. And if you don't know a thing about woodworking, it might show you a thing or two. Not that it will be any help when you actually pick up a hammer. [Brighton Exchange via Design-Milk]
