Cartão Heaven's Bridges, The Rainbow Poem

The front of this card has a spectacular image of a double rainbow over a mountainous coastline during a sunset, and the inside has a wonderful poem titled The Rainbow by Christina Rossetti: Boats sail on the rivers, And ships sail on the seas; But clouds that sail across the sky Are prettier than these. There are bridges on the rivers, As pretty as you please; But the bow that bridges heaven, And overtops the trees, And builds a road from earth to sky, Is prettier far than these.
