A drawing is inadequate, this requires a 3-d diagram. But one must be
careful how it is transmitted -- if as a raster image then the receiver
has a 50%% change of getting it inverted....
I think you need to use one of the parity-violating decays, but the
details are not obvious.... And I'm not sure that would work, as I
believe they actually violate CP, not just P (but on earth there's no
way to apply C to a bismuth nucleus).
C = charge conjugation, P = parity inversion.
But no matter
-- just have them send a SMALL object before coming, and
let us observe whether it annihilates or not.
