Batman comics date back to the 1930s. Over the years, they've become an icon in the comic book world. The longevity of the series is a testament to its enduring appeal and the creativity of the writers and artists involved.
Old comic Batman typically had a more gritty and noir feel. He relied more on his detective skills and physical prowess. Also, the villains were often presented in a more menacing way.
Well, Batman's age in the comics is kind of fluid. It depends on the creative direction of the writers and the particular story arc. Usually, though, you can expect him to be around 40ish, give or take a few years depending on the context.
