This might be my very favorite promotional flyer from The Sands Hotel. It is certainly from a very early (circa 1956) appearance by Sinatra at the location he would ultimately put on the map. It was during this period that Frank Sinatra met Bill Miller, his long-time pianist and friend.
This is a very classy piece, indeed.
What a wonderful flyer! Would it be possible for you to send me a bigger picture of this flyer in order I can put it on the desktop of my computer?
