Hi David, Your GBB is a little puzzling. There is a card showing 500 "GBB" chips (150 White, 100 each Navy, Orange, Green and 50 Yellow) shipped to William J. Wegmann at 2206 American Bank Bldg., Corondelet St., New Orleans on 2/6/65.

There were 3 other orders shipped to William J. Wegmann at the same address:
8/2/57---500 "JTC" in Blue, Gray, Green, Orange, Yellow
12/15/61---500 "MTW" in Green, Navy, Red, White, Yellow
12/2/65---500 "ARC" in Green, Navy, Orange, White, Yellow

Another order shipped to August A. Wegmann at the same address on 4/24/58 for 100 White "GUS"

It seems that they had more than one game going and we don't know where any of them were, except that they were probably somewhere in the New Orleans area.
