Like everything else made for a casino......they would change vendors and designs on the cups (ever so slightly) I think it's the "Golden Nugget" casino that the cup "almost" looks the same, except you find out by looking at the bottom of the cup, there were 2 vendors and the printing at the bottom of the cup (one Solo cup is printed in red ink while the second is printed in black ink).

One, day I will have to get off my backside and take pictures of all the slot cups I have and get them in the guide.
