The seller is Nevadamint and his "me" statement says:

"The Worlds Largest Casino Gambling Museums & Collectible Museum Stores. Strip Location, At the Tropicana Hotel Casino in Las Vegas Nevada. doing Business as Casino Legends Hall of Fame," Musuem Store". Downtown location..."Lost Vegas" Gambling Museum & Store on Fremont St. Inside NEONOPOLIS MALL."

That's what made me think it might have come from there.
