Moonlight postcards have a magic appeal for everyone. In the Golden Age of the postcard they were a mark of any right-thinking town, to show off their modern way of life and their up-to-date streets.
Trees benefit mankind more than any other plant. Poems often bring smiles to our faces. If you combine trees and poems, the way Joyce Kilmer did, back in 1913, and add a postcard or two; what do you get? You get a pretty good recipe for happiness.
