CHICAGO — Lollapalooza brought around 100,000 people to Grant Park a day, and while they headed home with new memories, they also let behind hundreds of items – some of them pretty important – that they’ll need to reclaim soon if they want them back.

Thanks to a partnership with Chicago-based Crowdfind, the treasures of the festival’s Lost and Found are all listed online. Among them: 300+ (totally legitimate) IDs, credit cards, and other cards, 90+ mobile devices, 80+ sets of keys, two sets of EpiPens, and one very sad stuffed sloth.

Given plenty of Lolla attendees come in from out of town, hopefully those who left their identification behind realized their mistake before stepping into any airport security line.

Items can be claimed online by describing any engravings or unique qualities, or by knowing the passcode of the mobile device, and then picked up in person Tuesday between 9 a.m. and 5 p.m.
