The famed Tom Brady-autographed U.S. flag at the center of a lawsuit with the Patriots Hall of Fame last year can now be all yours -- if you've got some DEEP pockets.
TMZ Sports has learned ... the stars and stripes that Brady signed and then re-signed following a man's dispute with New England's HOF in 2021 is going up for sale on eBay later this month -- and its starting price tag is $299,999.
Unclear what it's ultimately expected to sell for ... but we're told the profits will go to a good cause nonetheless.
