What Is This?

Every morning on the LIRR, I pass this thing.  Sorry it's tough to see.  I had to take the picture through the window of the train and power lines got in the way.

Basically, it looks like a cell tower.  Next to the cell tower is an antique car placed atop a platform.  Attached to the platform is a sign that says "WB2AHK" on one line and "AOL.COM" on the next.

Does anybody else see this on their way to work and wonder what it is?
