Offered here is a full set of the Flamingo HILTON, Laughlin, NV "Cool Bird" set of 12 chips, with serial number 776. I believe that the cage may have bagged and sealed this set (and others), but that may have been done at the factory in an effort to keep the full sets together.
I have purposely not opened the bag, and, in an effort to show all of the 12 different designs and the common reverse, I am showing a "QuickView" image from The MoGH's ChipGuide entry for this set.
This sealed set is offered at $75, which includes shipping to a US-only address, via an economy service. Available on a 1st come, 1st served basis, this offer will be cross-posted.
Thanks for looking! Jim
