OK! Here's one for the old timers, and new timers, and us inbetweeners. Can you look at an object like the tray below and tell approximately when it would have been made based upon the DEMISE or NON/DEMISE of the casinos shown on it?

Would they produce this thing AFTER the casinos were gone? No dates are on it! Picked this beauty up a couple of months ago and have no idea why they would make it or when!
