A somewhat obscure niche in the casino collectibles world is the collecting of luggage stickers with the hotel names on them. All the "grand hotels" used to have luggage stickers to go on the guests' suitcases when they left. You seldom see them anymore. Some of the Las Vegas hotels did have them (Sal Sagev, for instance) but they are mostly the foreign casino hotels that you find now.

Here is one from Peru, along with a chip from their casino. The stickers are usually round, square, oblong, rectangular, etc, but here's one that is pennant shaped. I can't figure out what the picture shows... looks like some red-coated guards outside a tower circled by sand bags. Maybe terrorist problems in Peru?
