Abby Powell is an Austin-based photographer and blogger, whose work I've admired for quite some time now. Abby captures the most dreamy images with her vintage cameras, and her 2011 calendar features one of these photographs each month.
If you're a lover of graphic design, then Heather Lins' 2011 calendar is for you. She has interpreted each month typographically, with the design printed on a wood veneer card.
Camilla Engman is someone whose work is difficult to explain, but impossible to forget. Her calendar features a nice range of her paintings and illustrations and of course, her beloved dog Morran.
Sometimes, having more than just one month at a time visible is exactly what you need, in which case, Miriam Bereson's yearly planner is the perfect solution.
