The Legionnaires featured were Mon-El, Lightning Lad, Brainiac 5, Cosmic Boy, Chameleon Boy, and Saturn Girl. All were illustrated by Dave Cockrum, taken from his Lore of The Legion feature in Superboy/Legion #202.
I came across most of these at some nostalgia store or some place in the late Seventies. I used them for pens and pencils for years until they cracked or broke during some of my moves. I think I still have the Aquaman one somewhere....
Who else would LOVE to see an actual Legion Toon Tumbler?
Seems like these pics were originally from Computonet dom com! I found them by doing an image search, but as LSH fan Michael noted below, you can find the entire collection here at Sidne Ward's Legion page. Nice job, Saturn Girl~!
And for completists' sake, here are the four Reserve and Honorary Legionnaires, too...!
