In Boys of Steel, Nobleman celebrates the amazing story of Superman creators  Jerry Siegel and Joe Shuster, two Depression-era teens from Cleveland .  Superman debuted in 1938 when Siegel and Shuster were only 24 years old.  Boys of Steel  received multiple star reviews and was named an  American Library Association Notable Book . 

Bill the Boy Wonder illuminates Bill Finger's role in the creation of Batman. Finger, a Jewish writer from the Bronx, came up with the original vision of Batman in 1939.  However, during the first twenty-five years of Batman comics, Finger's name only appeared once while  all credit was attributed to Bob Kane. 

Due to Nobleman's research, DC Comics has attached Finger's name to recent productions involving Batman, such as Fox's TV show  Gotham and  Batman vs. Superman: Dawn of Justice (2016). Additionally,  The Bill Finger Award for Excellence in Comic Book Writing is given out each year at San Diego Comic-Con to two writers, one living and one deceased, who have not been properly recognized for their work.  This year, Hulu released  Batman & Bill, a  documentary based on Nobleman's findings chronicling Finger's career.
