This is an activation / download code to get Logic Pro direct from the Mac App Store.
Still unredeemed and completely legitimate (I.e. not a crack or anything else of that shady nature), but as far as i know, it works with USA App Store only.
Also, bear in mind that, once apple went the App Store route, they started selling logic and mainstage separately, and also discontinued Soundtrack Pro and waveburner. So this is for Logic only (Soundtrack and mainstage kind of sucked anyways, so it's a good way of getting just what you need without all the dead weight and added expense).
$150 via PayPal, and you get the code.
