Found signed hat at the Aus Open

Morning all

Yesterday when visiting the Australian Open, I parked my car at the MCG car park (which is still just $10!). Some Good Samaritan hung this wet red “The New Minimal” hat on my rear wiper by the time I got back. It’s obviously signed by a couple of people, and I assume they thought it was mine if it was on the ground near my car

But it isn’t! So in hoping some kid’s (or enthusiastic adult) tennis day wasn’t ruined I thought I’d ask if anyone knew someone missing a hat. No idea who the signatures are, so bonus points I guess if you can work that out too
