I have one these calenders for trade. It was given out by Stations Casinos for the Holidays.
I managed to get 2.
The top of the picture is the box it comes in the bottom is a day in history.
Each day has it's own page and tells you what happened when....
I will trade it for Las Vegas house chip/chips I do not have.
