They're all rescues
Mersh standing with a drink talking to the Hulk, who leans down to bump his fist. Mersh's reply is drawn as a heart-shaped balloon containing the single word Kitties; the Hulk's reads: Wow! THAT'S great! AND they're all rescues?
Two figures on an empty hillside, the Hulk filling the right two thirds and Mersh the left, with both balloons stacked in the open sky above. The fist bump sits at the exact centre and is the only point of contact.
Acid and olive greens through the Hulk against the coral of Mersh's shirt, over a cold blue hill and sky. The heart balloon is the only red.
Ink contour with washes laid inside it, the Hulk modelled with hatching and dry-brushed shadow while Mersh is left flat — the same device used elsewhere to keep him the ordinary man in the frame.
