[img=100611_calendar 2.jpg][img=100611_calendar.jpg]Amazon UK have the official 2012 Green Day calendar for sale at a reasonably priced £5.99 (about USD $9).

You can purchase the calendar here.

I understand that you can order from outside the UK from that link, while the amazon.com site currently says they're "out of print."

It's also available on another UK Website Calendar Club with this description...

[quote]The Green Day 2012 Official wall calendar has 12 fantastic images of the pop-punk legends. Since the world wide smash of Dookie to their latest offering of their live album (that due to obvious reasons will remain nameless here, but involves awesome!) they have sold in excess of 65 million records, which firmly puts them in the rock legends category. So enjoy the year with the Berkeley Trio.[/quote]
Judging by the preview pictures, it looks like the calendar is a collection of a few live shots from the last tour as well as some of the promo shots for the album 21st Century Breakdown.

Hopefully 2012 will bring more good stuff from the Green Day world!
