Unofficial but a bit of a holy grail for me! I saw a similar (but different- I believe it only said "if you are a false don't entry" in red block letters) rug online about ten years ago and could never find anything similar, or even locate the original picture, but fuck did I want it! Well, this past weekend at MDF a vendor had this in front of their booth. I assumed it was a one-off for personal use, but you know what they say about assuming, so I hit bro with ye olde "I gotta ask, is the rug for sale?"
Sure enough, they were making and selling them and I am now the proud owner of a cool fucking rug.
