Kids with guns executing other kids cup for House Hat

I found this at Goodwill next to all the discarded wedding toast glasses, plastic A's cups, and granny shot glasses. I have no idea what the story is behind it but for 99cent - I rescued it. It's definitely someone's art project but the grim imagery raises a lot of questions. Even my most twisted friends don't want it. I'm sure it'll ruin people's feng shui. It'd make a great gag gift for creating uncomfortable silences.
