Although some people have complained about the re-use of comic-cover art for VS cards, I personally do not mind it at all, especially if it

A) Is Good Art

B) Saves Money

That being said, which comic-book covers/panels would you like to see on a VS card, either as alternate art for an existing card or as a new card?

(and if it's a new card - what would that card be/do?)

It would likely cost more money if it was a popular cover.

A few off the top of my head:

The "bleeding S symbol" from Superman 75

The cover of the issue of Spider-Man when the Green Goblin tossed Gwen Stacy off the bridge

The Joker/Harley Quinn pose from "Mad Love"

Crisis on Infinite Earths # 8 (for when they finally do the Speed Force team)

Alex Maleev

Wolverine popping Sabretooth right before AoA, Mags tearing Apoc apart in Omega, ANYTHING foily w/ Doom 2099.

The new JSA #1 cover by Alex Ross for a new JSA plot twist. Best. Extended Art. Ever.

They need to have more Tim Bradstreet covers. His work in Punisher is amazing.

Thought I'm not a fan of reusing covers at all, if it must be done, here's what I'd like to see.

Superman For All Seasons #2
Action Comics #1 (already technically on Super Strength, but who wouldn't kill for some Joe Shuster love?)
Anything from Superman's Pal Jimmy Olsen when the covers were done by Jack Kirby
