Someone sent me a link to this auction this morning. Looks like they have some original concept art for a couple of old Williams bingo machines.

The two lots I thought were more interesting is original concept art for Williams Blue Chip.
On lot is the artwork that’s of the adopted design, the other appears to be concept art and more like a proposed design that was Un-adopted.
