Over the past few years, DC has fallen into the practice of dropping a "Teaser Image" for their upcoming major storyline every few months, and they really do the job. They're intriguing, and when readers see them, they get to talking about what all these pieces could mean, without ever really going back to see if anything panned out. It's a win for everyone
The last one we got was a Batman/First Thanksgiving-themed piece that hinted at the events of Batman Eternal -- which sounds really weird when you actually type it, but which definitely happened -- and now, we have an Escher-inspired tease at what might be happening in the upcoming Futures End event, specifically The New 52: Futures End #0, which is due out for Free Comic Book Day this May 3. Have a look at the full-sized image below!
