I have a glass swan dish, 7" long 5" wide, body of the bowl is 2" high, and the head of the swan is 5" high. Inlaid on the inside is "Harrahs Reno, Nevada, New year 1968, Frankie Laine/Myron cohen, Headliner Room". Has anyone seen any of these? What were they used for? Can't scan it on my flatbed! Thanks for any information. Doug in Kingman, Az. R-3744
