I like the art. I have always liked the stylized art of propaganda posters (old school stuff).  Not 100% sure what exactly draws me to it, but drawn to it I am.

Taken from the original story:

Thomas is selling a 7"x11" version for $32.30 and an 11"x17" edition for $34.10, which sounds like a lot for a calendar, but it's a deal when you consider that just buying an individual 11"x16" poster from his shop will set you back $11.95. This way, you can own them all without needing to spend $140+.
