Spiderman showed of his acrobatics today in Rockefeller Center in New York underneath a giant 11-foot-tall, 21-foot-wide spider.

Spiderman, also known as Craig Henningsen from Broadway's "Spiderman: Turn Off The Dark," helped unveil the bronze sculpture by the late artist Louise Bourgeois outside Christie's Auction House today. The outsized sculpture will be auctioned off Nov. 8 during the Postwar and Contemporary Art Evening Sale.

The Spider traveled across the country from the Napa Valley, in pieces, to arrive in New York. It's expected to sell for somewhere between $4 million and $6 million.

The sculpture is the second largest spider sculpture in creation, according to Christie's.

Bourgeois, the first female artist ever to receive a retrospective from the Museum of Modern Art, crafted six spider sculptures during her career. Some of the smaller spider sculptures have sold for $5 million, according to Christie's. Three of the spiders are currently on display in museums.

"This spider has a certain delicacy, as if it is just sitting there waiting to move," said Laura Paulson, the deputy chairman at Christie's America. "It's feet are very spindly and ready to crawl."
