"ATP, a year on banners", no...
"Blasts from the past"?....no, we need a catchy name to indicate....
"Banners: 365/12/1"?...hmmm, maybe? There are 365 banners in the year, we all nominate a banner from those 365; once nominations are closed we have narrowed down to our 12 favorite banners, and finally we vote for our favorite banner of those 12 and we select 1 winner.
(I wish I could think this clearly first thing in the morning!)
