mid-century green-blue background with a woven look.
Done in a traditional "atomic" barkcloth style with abstract shapes mixed with lots of Hawaiian imagery - surfboard, hibiscus flowers, Diamond Head, palm tree, ukulele, pineapple, tropical fish, thatched roof, beach umbrella, coconut-shell drink, waves, volcano, tiki mask, tiki torch, a Hawaiian canoe sail, and lots of tropical foliage.
