This is the official Rat Pack Poster It measures 24 x 36 inches. This poster has recently gone out-of-print! Note: There are many cheap knock-offs of this poster. They use inexpensive paper that gets saturated by the ink and makes the image too dark. If you can't see the bottom of Sammy's label in the light (near Sinatra's hand), then it is probably a cheap knock-off. The name "The Rat Pack" was first used to refer to a group of friends in New York. Several explanations have been offered for the famous name over the years. According to one version, the group's original "Den Mother," Lauren Bacall, after seeing her husband (Bogart) and his friends return from a night in Las Vegas, said words to the effect of "You look like a damn rat pack." "Rat Pack" may also be a shortened version of "Holmby Hills Rat Pack", a reference to the home of Humphrey Bogart and Lauren Bacall which served as a regular hangout. Visiting members included Errol Flynn, Nat King Cole, Mickey Rooney and Cesar Romero. According to Stephen Bogart, the original members of the Holmby Hills Rat Pack were: Frank Sinatra (pack master), Judy Garland (first vice-president), Bacall (den mother), Sid Luft (cage master), Bogart (rat in charge of public relations), Swifty Lazar (recording secretary and treasurer), Nathaniel Benchley (historian), David Niven, Katharine Hepburn, Spencer Tracy, George Cukor, Cary Grant, Rex Harrison, and Jimmy Van Heusen. In his autobiography The Moon's a Balloon, David Niven confirms that the Rat Pack originally included him but not Sammy Davis, Jr. or Dean Martin. The 1960s version of the group included Frank Sinatra, Dean Martin, Sammy Davis, Jr., Joey Bishop, Peter Lawford, and for a brief stint, Marilyn Monroe, Angie Dickinson, Juliet Prowse, and Shirley MacLaine were often referred to as the "Rat Pack Mascots". The post-Bogart version of the group (Bogart died in 1957) was reportedly never called that name by any of its members ?? they called it the Summit or the Clan. "The Rat Pack" was a term used by journalists and outsiders, although it remains the lasting name for the group. Often, when one of the members was scheduled to give a performance, the rest of the Pack would show up for an impromptu show, causing much excitement among audiences, resulting in return visits. They sold out almost all of their appearances, and people would come pouring into Las Vegas, sometimes sleeping in cars and hotel lobbies when they could not find rooms, just to be part of the Rat Pack entertainment experience. The Rat Pack's appearances were of unprecedented value because the city would always become flooded with high rollers, wealthy gamblers who would routinely leave substantial fortunes in the casinos' coffers. The marquees of the hotels at which they were performing as individuals would read, for example, "DEAN MARTIN - MAYBE FRANK - MAYBE SAMMY" as seen on a Sands Hotel sign.
