Reader interest in first appearances
Collectors value first appearances for their rarity and historical value, while many regular readers are interested in viewing how their favorite characters were originally portrayed. Reprints of first appearances are often published, both as single comic books and in trade paperbacks, usually with other early appearances of the character. Marvel Comics' "Essential" line has become popular by giving readers an affordable glimpse into characters' early history.
Historically, first appearances tell the origin story for the character, although some, such as Batman and Green Goblin, remained dubious figures for several issues. Modern writers prefer to tell a character's origin across an entire story arc or keep a newly introduced character mysterious until a "secret origin" issue. Some fans consider this a gimmick and prefer the older method.
The artistic merit of many first appearances is debatable. The events portrayed in most famous first appearances are continuously retconed, rebooted and/or expanded upon by subsequent writers. Like many golden and silver age comics, first appearances often become dated and do not fit the modern portrayal of the character.
However, some first appearances are considered classics. 1990s-era Spider-Man writer Howard Mackie said that his favorite story featuring the character was his first appearance and origin story in Amazing Fantasy #15 (August 1962), stating that writer Stan Lee and artist Steve Ditko "gave us everything we needed, I wanted or could ask for in the least possible space. Every single person who retells the origin never improves on the original, they simply expand it."
