Honolulu Paper Company, Territory of Hawaii, is one of only a handful of publishers of Hawaiian post cards from the early 20th century. This being a white border style card, it most likely date from 1915 to around 1930. This card was printed by C. T. American Art of Chicago and it shows one of many cane flumes then existent on the island of Hawaii, used to move the sugar cane directly from the highlands to the mill. The condition is excellent, some would use the phrase "near mint." It is free of any damage or wear and was kept unseen (away from light) in an album of similar cards for many years, thus the colors are likely as good as the day the card was purchased. You won't likely find one in better shape. It is numbered 93186.
