A kid pocketed this from my binder and it was brought back like this, is there any way to reduce the damage?

I need some advice. I left my binder unattended cause I thought it'd be fine. They were really excited and polite, so I left it with them to browse. This was completely on me 🙁 I fully understand I'll never get it back to mint condition, but it just feels sad to see it in this state

I've seen repair work online, but they've never shown cards this bad very often. Any idea what I can start doing? Will the same methods work for this one?
