Have some interesting and / or humorous Windows Phone fan art? Or do you simply have an awesome photo containing a handset that you wish to show off? If you share it on Facebook with the Windows Phone team, they may well include your submission in their album.

From the previous competitions we've held here at WPCentral, we know our reader base is bursting at the seems with talent (we have to suck up to you guys at some point, right?), so it'll be interesting to see what you call come up with.
