batgirl pinup

i bought this on ebay. a guy was cleaning out his collection of commissions (mostly cheesecake). i've always liked batgirl, and what struck me about this image was her breast size. most of the free-lancers selling drawings on ebay draw these ludicrous clown-sized jumbo breasts. but this batgirl is very much in proportion. this piece also has a nice fluid style. the artist is someone named Chabot. if anybody can help me identify this person, i'd love to give proper credit.
