So, I've added PSD Calendar templates to my custom print store. You can use them any way you wish with personal art/photos of yours to create your very own personal poster calendar. And get it printed through me for the best quality poster! Here's a preview of a poster calendar image I made for a previous client. :)

They can be vertical, horizontal, text layout anyway you want, etc.

Custom 17"x22" poster prints are just $12 each.
