This Batgirl #38 comic book features an VERY HARD TO OBTAIN sketch by Stanley Artgerm Lau. This piece in particular features Stephanie Brown as Batgirl. Stanley Artgerm Lau notably had a 6 issue cover run on the Batgirl series in 2010 which was well received by fans skyrocketing his career in the comic book industry. Artgerm has recently adopted a daily lottery system at conventions for commissions instead of first come first served making it difficult to get a sketch. Example: this past SDCC, myself and my husband tried all 5 days to get a sketch and was not selected any of the days.
