A. E. Schmidt made some cues in St. Louis back in the 60s and 70s that were called Minnesota Fats Professional cues. I don't recall them having any sticker on them saying that and they didn't have any logo on them, but that is the way they were advertised in their catalog.
Here is a page from one of their old catalogs.
The MF-11 and MF-12 were made with Brunswick Titlist blanks.
In edit: The gold sticker below the joint may have had Minnesota Fats written on it, but I'm not sure. I can't remember from that long ago.
