Some additional trivia...
The property started as an entity named "Holiday Gifts, Inc." in 1971 and it evolved into a slots-only place named the "Slot Joy'nt". Founded by Norbert Jansen & his wife. The slowly expanded it to the Boardwalk Casino and added a few table games, over time. Eventually went public as a small-cap stock "Boardwalk Casino, Inc" when lots of companies in the gaming sector were going public. With those additional funds, upgraded existing rooms (and added additional rooms, to meet standards for Holiday Inn franchise ( and important conection to their worldwide reservations system). The stock climed initially, but soon returned to earth. Mirage had boxed-in the Boardwalk from further expansion by buying or controlling land on all sides, including the jointly-owned Monte Carlo. The then-CFO of the Mirage, Dan Lee, did an intricate assemblage of land deals, then orchestrated the purchase of the Boardwalk Casino, Inc. Norbert Jansen, founder, had died, and his wife/widow owned quite a few shares. (There's an interesting article about all this in "CFO Magazine" from a few years ago)

Gene is correct about the use of the Holiday Inn name -- only a franchise. Dates in TCR are correct.

BTW, I have the IPO brochure & annual reports from the Boardwalk, during the time it was publicly-held. The IPO is a kick. It has thatcolorful clown on the cover, in contrast to most buttoned-down financial reports!
