Unusual black-and-gold metal invitation from Caesars Palace for a black-tie event honoring the Frank Sinatra, 5.5 x 8, reading, in part: "Caesars Palace cordially invites you to a loving tribute to Frank Sinatra on the occasion of his fortieth year in show business, December 12, 1979." Among those in attendance at the event were Dean Martin, Cary Grant, Harry James, and Don Rickles. In fine condition.
