The city is auctioning off one of the 30 "Champions Way” street signs that hung on Broadway during the Knicks parade, officials said Wednesday. 

One lucky fan will snag the handcrafted blue-and-orange sign, which was made at the city Department of Transportation’s Sign Shop in Maspeth, Queens. 

The sign measures 36 inches by 9 inches and is made of a durable aluminum material, the city said in a release. 

Bidding began at $100 on Wednesday morning and will last until 8 p.m. on Wednesday, Aug. 12. The auction is taking place via the city’s online surplus action website. 

As of 11 a.m. Wednesday, bids were already up to $390, with more than 100 people viewing the listing. 

The Knicks won their first NBA title since 1973 in mid-June, beating the San Antonio Spurs in Game 5 of the NBA Finals.

“The Knicks championship celebration was a once-in-a-generation moment for New York City, and these commemorative street signs capture the excitement, pride and history of that unforgettable day,” Department of Citywide Administrative Services Commissioner Yume Kitasei said in a statement.

“Through DCAS’ surplus property auctions, we’re thrilled to give fans the rare opportunity to own an authentic piece of New York City and Knicks history,” Kitasei added.
