An original 1971 U.S one sheet for the film Skin Game, an American comedy western directed by Paul Bogart and Gordon Douglas, and starring James Garner and Lou Gossett.
Two western con man Quincy (James Garner) and Jason (Lou Gossett) swindle slave owners in backwater prairie towns in 1875 into buying a free man, and later share the profits when he escapes captivity. It's an effective scam for these smart and nimble schemers - until they cross paths with an equally clever con woman (Susan Clark) and an irate former customer (Edward Asner). 
The premise of the film sounds absolutely painful, even by 1970s standards, but this seemingly tasteless pic survives on its genial humor, the likability of the popular lead actors and the director's light touch. This movie is way smarter, way edgier in terms of humor and commentary than you'd expect.
