This one is a bit weird.
What you are looking at is a scene from the third issue of DC's mediocre late-Eighties crossover Millennium. Specifically, it is the potential Russian New Guardian getting his head blowed off because, you know, evil empire. Millennium: the series that shows every country on Earth in the worst possible light. Except China, as I recall.
What messed me up about the whole thing is a two-parter: firstly, I only had the one issue of the series, so I had absolutely no idea what was going on. And secondly, the toned-down nature of the headshot in question totally made me think that the guy's head was popping like a blown bubble. Why was the idea of someone with a bubble-head so disturbing to Young John? No one will ever know.
By the way: here's the best thing about Millennium.
Booster Gold saves the day by containing an exploding Manhunter, and then Batman calls him "m'boy."
