Although I can't say I've really been digging this particular tie-in to Blackest Night, I really like the variant cover to issue #3 of Blackest Night: Titans. It features George Perez's homage to one of the greats, himself, as he re-imagines the cover to New Teen Titans #30. That book featured the introduction of Terra and started what could arguably be called the greatest Teen Titans story ever. At least, I'd probably argue that.
