In comics, the first issue is where the story starts and the legend begins.
For readers, a print copy of issue one can be hard to find and expensive to buy. But those rules don't apply to tablets, laptops and smartphones.
Marvel Entertainment, home to the Fantastic Four, the X-Men and the Avengers, among others, is making more than 700 first issues available to digital readers starting Sunday via its app and website.
David Gabriel, senior vice president of sales, says the titles go from the 1960s Silver Age to contemporary issues with characters including Wasp, Mr. Fantastic, Power Man and Iron Fist.
