a) QoD 10/1/2014: "What ever happened to the giant Big Six Wheel at Vegas World, and the 'space junk' hanging from the ceiling?"
Montage includes images of the exterior of Vegas World, including the mural referenced in the answer, plus the Big Six Wheel and assorted "space junk," the Galaxy Bar, and Stupak himself with a vision of what the future Stratosphere Tower would look like.
b) QoD 6/2/2014: "The recent residency QODs have me wondering about Debbie Reynolds' history in Vegas. I know for awhile she owned a small off-Strip casino where she performed but how did all of that come about?"
Images reflect the Debbie Reynolds casino in some former incarnations as the Royal Inn and Paddlewheel, and latterly as the Greek Isles, plus a photograph of Ms. Reynolds herself with Dean Martin.
Enjoy!
