In his 1954 book Seduction of the Innocent, German-American psychiatrist Fredric Wertham warned that comic books were a serious cause of juvenile delinquency. The book was taken seriously at the time, and was a minor bestseller that created quite a stir among alarmed parents. As a result, a U.S. Congressional inquiry was launched into the comic book industry. In response, comic book publishers voluntarily established the Comics Code Authority to self-censor their titles.
Plastic Man's sidekick is Wolfgang "Woozy" Winks. In his first appearance (November 1942), Woozy saves a wizard from drowning, and is rewarded with a spell that causes the forces of nature to protect him whenever he is in danger. Later stories ignore this ability, and Woozy simply becomes Plastic Man's inept assistant.
The Sanctum Sanctorum is the residence of Doctor Strange.

Stan Lee originally wanted the Hulk to be grey because he wanted a color that wouldn't suggest any particular ethnic group, but colorist Stan Goldberg had problems with the grey coloring, resulting in different shades of grey, and even green, in the first issue. The Hulk's color was subsequently changed to a more manageable green, and the original color was explained away as a second Hulk persona that is usually suppressed by the stronger Green Hulk.
Ally Sloper's Half Holiday was a British comics magazine, first published on 3 May 1884. It featured Ally Sloper, a blustery, lazy schemer often found "sloping" through alleys to avoid his landlord and other creditors, and is considered by most comics historians to be the first comic strip magazine to feature a recurring character.
The founding members of the X-Men were Cyclops, Marvel Girl, Beast, Angel, and Iceman. Wolverine didn't join the team until Giant-Size X-Men #1 (1975), but he quickly made up for lost time, becoming the most popular X-Men character and eventually earning his own comic.
