The person that originally posted the image got the QR from a dream address, so I am unsure if it is posted publicly anywhere. I found these that are fairly similar if you are interested: http://potofu66.blog.fc2.com/blog-entry-73.html
These are as close as I can find. Unfortunately the tumblr they are from is no more. However this reposter on twitter (which what they are doing is bad) has posted some pics. The brown border is darker but it's still pretty close, if not from the same creator, just a different colour with the border.
