This Wednesday August 5, 2009, six vintage Hawaiian tourism posters are to be auctioned in New York
There are reproductions of the posters sold in some shops - but only the first print originals are coveted by collectors.
The posters have been verified, with each estimated to sell at $600-1,000.
Each poster refers to an airline - including three for United Air Lines and three each for TWA, Matson Lines and Pan American.
The artists' names appear on some of the works - including John Atherton, Stanley Walter Galli and David Klein - but none are signed by hand.
