House ad for Batman and the Outsiders v.1 #32 (April 1986); printed in Detective Comics #560 (March 1986)
Art pencilled and inked by Alan Davis, reversed from the cover of BATO #32:
Note that in the ad Halo's aura is yellow, her "brilliant light" power, but on the cover it's blue, her "holographic distortion effect" aura. Which means
- On the cover, Halo can't be bothered to show up for Batman's leave-taking and instead just sends a halo-graphic image;
- I know waaaaaay too much about Halo.
