Micronauts Marvel Concept Art

This gorgeous piece of art is the ORIGINAL CONCEPT ART created for the Marvel Micronauts comic series. Pencilled and inked by Bob Hall, this piece was used to "sell" the idea to Marvel execs to create the series based on the popular Micronuats line of toys. Several years ago, after having purchsed this piece from Mike Burkey, I communicated with artist Bob Hall who confirmed that this would have been the first piece of Micronauts comic art ever produced. I have had a couple of individuals email me to tell me that they believe that this piece was actually published. Would love to find out where.
