Comic-book characters are experiencing something of a renaissance, inspiring wildly successful movies, television series, video games, and now pens. The Italian pen maker Montegrappa has introduced a new line of eight pens inspired by heroes and villains from the DC Comics universe. In contrast to the gritty takes on these iconic characters that are popular today, the Montegrappa pens are inspired by their campier, silver-age (approximately 1956 to 1970) incarnations. Each pen is priced from $395 to $475, depending on nib type. (<a href="http://www.montegrappa.com/products/writing_instruments/dc_comics/i…
