FILE - In this Jan. 6, 2011 file photo, collector John Maloof matches title tags with photographs hanging at the Chicago Cultural Center for the first ever exhibit of Vivian Maier's photography in Chicago. Maloof, who bought a storage box at auction stuffed-full of her negatives for $400 in 2007, and later, bought 100,000 more negatives, is at center stage in the dispute over the lucrative copyrights to the photography. Booming interest in the subject of a documentary up for an Academy Award Sunday, Feb. 22, 2015, "Finding Vivian Maier," has sparked the legal battle. (AP Photo/Charles Rex Arbogast)
