Since 2008 is the 50th anniversary of the Legion, I thought they should be up next for the fave 5. DC Comics has some stuff planned out for this year, including the awesome "Superman and the Legion of Super Heroes" story which should be ending in next month's Action Comics.
Legion of Super-Heroes v2 #300
This was the 1st Legion issue I ever picked up, about 15 years ago. I still catch myself reading it from time to time!
Legion of Substitute-Heroes Special #1
Because of this special, I LOVE the subs!
Adventure Comics #312
Great story of sacrifice from the Legion's early days, and also an inspiration for "The Lightning Saga"
Legion of Super-Heroes v2 #293
If you haven't read "The Great Darkness Saga" run to your LCS and find them! Awesome Legion story, the one that got me totally hooked!
Superboy and the Legion of Super-Heroes (paperback, 1977)
Long Live The Legion!
Since I went through my 5 favorite Superman covers from long history, I thought I'd add 5 more, this time featuring Superman in action. It's also fitting as today is Superman's birthday...
Action Comics #300
How will he get out of this one? Another good Silver Age Superman story!
Action Comics #419
I love the style of this cover..
Superman #242
Very epic!
Superman vs. Muhammad Ali
Classic!
Action Comics #648
George Perez, Superman AND multiple Brainiacs? Definite win here!
Supergirl v3 #1
Supergirl v3 #80
I miss Linda :(
Superman/Batman #13
I love Michael Turner's work!
Supergirl v4 #22
This cover is full of win!
Action Comics #555
This was the first comic I ever picked up with Supergirl in it. This issue was part one of a 2 part celebration of Sgirl's 25th anniversary (Just as the Superman/Batman arc rebooting her was for the 35th)
New segment! Every Thursday I'll post my top 5 covers of a comic subject. Since this year is the 70th anniversary of Superman, I thought I'd try to pick my favorite covers from his long history. Here's the first 5:
Superman # 233 
I've always loved this cover! This is from the era where Superman was to be "de-powered" by having all Kryptonite on Earth turned into ordinary lead.
Superman #670
The new Superman family, nuff said.
Crisis on Infinite Earths #7
One of the most iconic covers in comics history, this issue is where the original Supergirl died sacrificing herself for her cousin.
Superman [vol.1] Annual #10
An awesome story showing once and for all the Pre-Crisis Superman really was the greatest of all time!
Superman #347
When I first saw this I thought "An enemy Superman can't touch? This has to be good..."
