A very very very custom calendar, with full bleed tabloid-sized sheets and different layouts for every page (including different orientations for several months). All family images came from pictures taken during the prior year, except for the June and December "heritage" images.
Printed and distributed to all adult members of the family for less than what a template-based calendar of a smaller size would cost.
(There are more than twelve pages in the montage because two cover options are included as well as a mockup of a page for a 2011 calendar.)
