Cartão Thoreau's Sunset (Dark Text) Greeting Card

A child watches an ocean sunset and the clouds appear to form a castle. Text overlaid on the clouds states, "If you have built castles in the air, your work need not be lost; that is where they should be. Now put foundations under them." The quote is from "Reflections at Walden" by Henry David Thoreau. The quotation is printed with dark text to give emphasis to it.
