What You See in Sunset Park: Holiday Carts

These three shopping carts have been chained to a street sign for almost a week. Could it be street art?

Or just a sad, deserted form of transportation for a couple of stuffed animals?

The teddy bear looks more forlorn than the snowman despite his more comfortable placement.

There's a nice shiny chain holding them onto the sign.

What's your guess? Deserted? Lost? Stolen? Waiting for a pick-up?
