Go onto Deviant Art and browse "Legion of Super-Heroes." You will find all sorts of Legion goodness (and some weirdness). That is how I first came across Peter Vale, the "pen" name of artist Pedro Vale, Jr.
Here's an absolutely fabulous work of Legionnaire Tyroc vs Marvel villain Songbird. Check out the details!
There's also quite a few illustrations of Zatanna, Superman, and former Legionnaire Supergirl.
So check Peter Vale out on his Deviant Art page!
