I picked up my first Rolling Rock Beer stadium seat about a year ago. It is a legit seat. The iron base is solid and the seat and back are hard moulded plastic.
My son and myself were just at a hockey game at the Verizon Center in DC to see the Capitals. I commented to him that we have nicer seats in our bar than they do at the Verizon Center.
I suppose these single seats were promotional items for beer distributors.
I contemplated painting them but decided I'd rather keep them in their original state.
The seat number on both (or all produced) is the familiar "33".
Actually a better looking seat than my Veteran Stadium seats.
