Glossy hard cover, in typical Whitman used condition. These books were cheaply made for an audience that was less than fastidious about caring for their books. Cellulose laminate on the front cover is pealing; the corners are rubbed throug to cardboard and the hinges are reinforced by tape. The paste-downs have pulled away a bit from the boards, so the text block is cocked within the casing. Pictorial endpages, all edges stained red. 

Rin Tin Tin or Rin-Tin-Tin was a male German Shepherd born in Flirey, France, who became an international star in motion pictures. He was rescued from a World War I battlefield by an American soldier, Lee Duncan, who nicknamed him "Rinty". Duncan trained Rin Tin Tin and obtained silent film work for the dog.
Rin Tin Tin was an immediate box-office success and went on to appear in 27 movies. 

After Rin Tin Tin died in 1932, the name was given to several related German Shepherd dogs featured in fictional stories on film, radio, and television. Rin Tin Tin Jr. appeared in some serialized films, but was not as talented as his father. Rin Tin Tin III, said to be Rin Tin Tin's grandson, but probably only distantly related, helped promote the military use of dogs during WWII. Rin Tin Tin III also appeared in a film with child actor Robert Blake (Baretta) in 1947. 

Duncan groomed Rin Tin Tin IV for the 1950s television series , but the dog performed poorly in a screen test and was replaced in the TV show by trainer Frank Barnes's dogs, primarily one named Flame Jr., called JR, with the public led to believe otherwise.
