I found this really cool card / stationary company, Quill & Fox, on Young Blood Gallery's site. They are based out of Portland, Oregon and they design the sweetest little cards. I love this Valentine's Day Collection they just released.
Below are some samples of their everyday stationary and postcards, you can also see some of their custom print work in their lookbook.
If you're in the market for some fantastic handmade print-work like this, Young Blood Gallery is currently hosting a show called Go South: Southern Printmaking.
