After the (semi-failed) implosion of the Pontiac Silverdome last year, you might have thought all your chances to own a piece of Detroit Lions and Michigan history were gone.

Not so.

You can soon own a (literally) giant part of that history: The MDOT road signs bearing the Pontiac Silverdome’s name are going up for auction soon.

The Detroit News reports that the two green aluminum signs that are about 7 feet by 14 feet, weigh 225 pounds, and are in good condition.

One reads "Pontiac Silverdome Exit 39", and the other "Pontiac Silverdome Next 2 Exits".

Interested? The auction runs Sept. 10-24 at Mibid Auction.
