Todd's career began in 1977 in DC Comics' production department. While on staff, Todd tried many kinds of work including writing (TALES OF THE GREEN LANTERN CORPS, THE OMEGA MEN), but found lettering and logo design suited him best. After leaving staff, Todd continued to work for DC and other companies. Notable projects he's lettered are THE SANDMAN written by Neil Gaiman and AMERICA'S BEST COMICS written by Alan Moore. In 2004 he co-authored THE DC COMICS GUIDE TO COLORING AND LETTERING COMICS. In 2007 Todd launched a website and blog at kleinletters.com. Original prints are for sale there.
