The Oasis portion of the Dunes opened in late 1982 or early 1983. I have a picture of the Dunes in 1983 with the Oasis casino attached. The Dunes closed it's doors in January 1993. The first time I had seen a Full Graphic inlay by Paul Son was the latter half of 1993. (That was a long time ago and I could have my years wrong). So I am wondering if the chip was made as a sample by Paul Son since I have seen a couple of different inserts used. Just Wondering.
