I finally found something else on Fullgraff and tobacco. Frank G. Fullgraff, as it turns out, has a patent to his name, for an illuminated advertising display sign that folds ("Cigars" in the image example). Filed in 1923, granted in 1927. His attorney was an 'Arthur L. Kent', I believe it says, who does not appear to be his counsel in his lawsuit a decade before.
The first image is from it's section in the
Official Gazette of the United States Patent Office 356, page 476, and the second the actual patent. Apparently he had some competency with electronics as well as his many other interests.
And, just linking the side research from last month into the ledger and Turkey Red that stemmed from this so everything can be traced from one place:
