JLA/Avengers #4 – NM – 2004 (Marvel/DC)

NM — Bagged and boarded. The crown jewel of superhero crossovers — Busiek and Pérez poured everything into this finale and it shows. Pérez's artwork is a jaw-dropping feat of density and craft, cramming decades of continuity into panels that reward every reread. A true once-in-a-generation publishing event that will never be reprinted, making physical copies the only way to own it.
