That would be Betty and the artist is Bruce Gerlach. I couldn't find a lot of information about how many cards Gerlach did as eBay shows just one more so I contacted him through his website and he promptly responded to let me know he did 53 that were inserted in packs and an additional three that were returned to him as part of his payment (a common practice in sketch cards).
Miss. Betty is drawn in a very recognizable manner. Gerlach did a good job of capturing her happy spirit. Granted, there's not a lot of color but I really like the textured look the card gts with the painted blue background.
Two packs in and this Archie March of Dimes Sketch Cards Series stuff is fun. And proceeds go to charity.
