The image here on the right is obviously by Adam Hughes. This is the box art for a new perfume called Heroine. Sales benefit the comic industry charity HERO. Supposedly, it smells like Nepalese amber, East African patchouli, dark musk, apple blossom, petitgrain, aged leather, skin musk, and rhubarb.
Anyway, it can be ordered online (natch) or through comic shops.
So Johnston wrote, "pop into you comic shore and ask f they can sell you some Heroine.
"Actually, be carefully with that last bit."
I was already laughing before the ending sentence.
