Oh, a note to Neilalien:
Thanks for the info on the Wand of Watoomb! I read that indeed-classic Spidey/Doc Strange team up oh so many years ago when I was a squirt, but had forgotten about it. I was thinking that particular object (one of the JLA/Avengers quest items) was Tiboro's wand.
One of my favorite late-60s comics was the Thomas/Colan issue of Doc in which he battled Tiboro. Colan was just out of his mind drawing that stuff!
