It's Caspar David Friedrich's picnic basket!
What a bleak vista to regard on a winter’s day - surreal, disturbing, hardly reassuring. Life is just a sweet, perishable thing dropped in the uncaring wastelands of ice and snow and sunless skies. What happened to the fellow who dropped this basket as he staggered across the frozen terrain? Why was he carrying unprotected fruits and vegetables across the Antarctic, anyway?
Inside, the depressing mood continues, as you’ll see.
