Great collection, yes the Sparkler box is VVVHTF, condition is another issue all together. I have some pix of a nice box Charles & Chad "Mibbage" sold on their store site some years ago. The dividers don't look original but still a very rare box.
I don't have a nipper Sulphide either Brad, don't feel like the Lone ranger. A nice find, especially in the shape it is and pretty well cantered on top of it.

Alley, Peltier & Akro are the only companies I'm aware of that made the (collector named) Superman mibs.. Never seen one made by Champion but I guess ya never know
I recognize the Peltier Superman pic you show as being from my Friend Terry Middleton's ( http://grandpamarble.com/ ) store site.
