Britney's Attack Umbrella Hitting Auction BLOCK

The green umbrella Britney Spears unleashed on a paparazzo after shaving her head in 2007 is hitting the auction block and at a decent price.

Daniel Ramos, the pap whose car Britney clubbed with the thing, says he's ready to part with the piece of pop culture history since he thinks Brit's in a good place. Plus he's making a movie and needs the dough.

Though he has floated the idea of the sale in the past, and now it looks like he's ready to make the move for good.

The umbrella is listed online with RR Auction and hits the block August 10th.

As for how much it could fetch, Ramos is thinking in the $50k ballpark, and has a favored spot for it to land.
