This is what appears to be a authentic Rock is King Rodney Mullen deck from World Industries. This board was released in 1992 with graphics done by Marc McKee and with out Rodney's knowledge. Apparently World knew Rodney would not approve of this graphic so they snuck behind his back and released while he was on tour. World then sent it to a few shops where Rodney was going to be doing demos and as the story goes the first time he saw one was when a little kid brought it up to him to be autographed.
