Hi Gary,

You've found a nice one. I've got the same tray but have only seen a couple others come up in the last two or three years. I've put a pic of a blue colored one that was on ebay last year along with a free games card at the bottom of this post. According to the date on the card it was used in the late 30's early 40's. By the way if I'm not mistaken tango was alot like bingo. I wouldn't sell mine for less than a c note and you might do better than that. I'd start it out with a low opening and a reserve that you can live with. Hope this helps.

Scott
