Variant covers aren't new. We've been seeing them for a while now. What makes a variant worth looking at is when it can stand out from the rest.

Today, Marvel has announced a slew of upcoming variants labeled as "Avengers Art Appreciation." Marvel is answering the question of what the Avengers might have looked like if they "existed throughout the ages." During April, the covers of your favorite series will sport Avengers covers in the styles of the world's greatest artists like Rembrandt, Michelangelo, Monet, and more. These covers will be done by today's artists like Alex Maleev, Michael Kaluta, Gabriele Dell'otto, Greg Horn, Gerald Parel and more.
