The rat pack consisted of Dean Martin, Joey Bishop, Sammy Davis Jr., Frank Sinatra, and Peter Lawford. They were best of friends and headliners in Las Vegas in the early 1960s. These are rare photos, some of which were never intended to be published. They are available in three editions, the most expensive of which is the Heritage edition which is worth approximately between $1,600 to 3,200. Take a look and enjoy in the old times.
