Here's a shot of GL vs. Grundy(he's not called Solomon Grundy as far as I can tell,just Grundy). Notice how his costume looks very similar to Kyle Rayner's Ion costume?
The GL symbol is also from Kyle's GL Jim Lee design.
No biggie by any stretch,but I would've thought they might have used Alan Scott's original Lantern symbol design and tweaked that instead of using Kyle's.
