Following a week filled with Samsung leaks, a new promotional banner from Sprint gives us a slightly closer look at the Galaxy S6 and S6 Edge ahead of their official debuts at Mobile World Congress next week.

While the other leaks have been blurry or not very revealing, Sprint’s poster, which was leaked by a “verified employee” on Reddit, provides a clearer, closer look at the devices and their new lockscreens — and yet again confirms the S6 Edge will be curved on both sides.

The poster also showcases the metallic frames with chamfered edges that both devices will carry, as well as their redesigned volume buttons, which are now separated, like on the iPhone. Unfortunately, the screenshots don’t tell us much about the new TouchWiz UI.

Sprint’s poster also reveals a prize draw that the carrier will be holding. Customers who register their interest in the Galaxy S6 and S6 Edge will have the chance to win one of six Galaxy S6 devices that will be given away each week for a limited time.

There’s every chance this poster is a fake, of course, but it seems pretty genuine to us. And even if it was thrown together by a fan, other leaks have confirmed this is exactly what Samsung’s new handsets are going to look like.

We’ll get our first official look at the Galaxy S6 and the S6 Edge on March 1, when Samsung announces both devices at an Unpacked event at Mobile World Congress. If you can’t be in Barcelona to see it, you’ll be able to watch the whole thing online.
