This is a check printed in black ink on black paper. It's hard to tell who it's written out to, or how much it's for, but maybe you could use that to your advantage!
You take the black pension check down to a check cashing store (seems like there's one of those things on every corner, these days) and toss it on the counter.
The clerk squints at you, eyes the check suspiciously, comes to the conclusion that they don't pay him enough to care, and forks over some Meat.
