Very rare original cabinet card (6.5" x 4.25") of Reuben the Guide, an African American man who operated a touring business, where he would escort visitors on trips to Tijuana and Old Mexico. He was a popular character.. The tourists loved his sombrero and five pointed star badge with its ribbon. On the back is signed, in period ink: "Yours for climate Reuben the Guide" It might be hard to see, but the bottom-front of the mount is embossed with the studio, Coonley, San Diego, California. This cabinet card is in very good antique condition with expected age wear, as shown.
