Imagine you hold an envelope, square and and stiff. You open it and, as you suspected, you find what is unmistakably a Christmas card.
On its cover is a painted landscape, a scene of serenity and peace. It shows a cold, deep, clear midwinter night. Snow-covered foothills speckled with gray and black stretch across the middle of the scene. Behind them, across the horizon, sheer, high mountain peaks reach into an ink-black sky peppered with with a thousand stars.
