Rifle Paper Co.
Basically, if Etsy threw up on a piece of paper, it would be the aggressively cute, in-your-face adorable, yet still somehow hipster printing house Rifle Paper Co.
Best to send to your friend who just moved out to Brooklyn or some desperately small town upstate. It's a postcard, so thankfully you won't have to write much as space is limited.
