You can find the yellow chip in the "pictograph" section of The Gaming Table, Gary. Page 281.

However, it's not much help as it is listed as Location Unknown, attributed to Kemah, TX.

In case any chippers haven't paged through the entire TGT, there is a section in the back containing photos of chips whose only marking is a pictogrsaph. These are a big help in identifying those with no words on them.

In another section in the back, there are also lots of reproductions of casino postcards to help you visualize what some of these old clubs looked like.
