Wired has published a photo essay about the AK-47.
The AK-47 has evolved over the years, which keeps it relevant to this day. This gallery charts the history of this terrible, remarkable weapon.
The photo essay has some technical mistakes and does not in fact chart the development of the AK-47, but it does feature some great photos.
UPDATE: A couple of commenters have pointed out that the above rifle is probably a fake or airsoft!
