Underoos Supergirl

This is an animation cel and the matching drawing used in the production of a 1973 commercial for Underoos, children's underwear. Since my understanding is that Supergirl never appeared in Superfriends, this commercial may have been the only time this version of Supergirl's costume was ever depicted in animation. This drawing is more elaborate than your typical animation drawing which makes me think this was a key pose. I have a Wonder Woman from the same set of commercials and it is much less detailed. This piece was originally shown with just the drawing, but I later acquired the cel and reunited them. The background is what the seller sent me. I have no reason to believe that it has anything to do with this particular ad. Another animation drawing, probably of a girl wearing the product is posted on my "Other Art" gallery.
