The DC Comics Blueline Edition series (at least up until the time of writing) consists of previously released DC Comics The New 52 figures based on Jim Lee’s art which feature a redesigned pencil sketch paint scheme. Also included with the figures are sketch cards featuring printed sketches by Jim Lee himself. It’s noteworthy to mention that the inaugural Batman figure, which was a 2015 SDCC Exclusive, did feature 150 units of hand-drawn sketches of Batman, The Joker, and Harley Quinn, which were inserted into random boxes sold during the convention.
