I used to go to Dallas on business regularly and stopped by Billy Bob's once in the 1980's. When I was there they had some kind of charity event where you could buy in, get chips, and play various table games. I played a little while and took home a bunch of souvenirs. The next time I saw any of these chips was in Spinetti's bargain bins several years ago. I wrote an article about them that was published in Casino Chip & Gaming News.
