Here's a neat item I've just purchased this week from a long-time original Resorts International employee ... circa; before Merv Griffin purchased the property.

Each roulette table had a 2" x 3" plastic plate like this one fastened to the table that indicated what design roulette chips were in play at that table. I guess it was to facilitate cocktail waitresses to know which table to present for redemption roulette chips given as tips. This particular platic plate has the soccer ball design engraved into it.
