Tango was an early 'bingo-like' game that was brought to Nevada from the amusement parlors in Venice, California. Here's a match advertising Bill Harrah's early operation in Reno. He bought the Heart Tango, a bingo parlor in Reno, in 1938 from Ed Howe for $3,000.

Could this have been the last place to offer Tango in Reno? In Nevada?
