Does anyone know what this is?
 

This has been sitting here for a while and I don't know what it is, what it's used for or a brand name. Can anyone help me with identifying it? I attached pictures.

Very interesting thing. Maybe it's some kind of attachment to the back of the bumper so you can put your feet on it?
