The scene begins on the bottom of page 10. No in-depth analysis here, I’m just going to let the scene speak for itself.
A definite game changer…
And if you need a reminder on just how good an artist Andru truly was, check out the Superman vs the Amazing Spider-Man treasury edition (the subsequent reprints that were printed regular comic book size DO NOT do it justice).
Last but not least, a piece that ran in Marvel Age upon Andru’s death back in 1993.
