An ‘Easter egg’ is defined by The Associated Press Stylebook as: “a hidden “surprise” in a program, a website, a DVD or a television show, such as an extra level of a computer game or a message.”  I was watching “Thor” yesterday when I noticed the poster pictured above on the side of a wall.  The Easter egg in question is the phrase: “Land Of Enchantment…Journey Into Mystery” on the poster (click to enlarge).

What makes it a surprise is that the character of Thor first appeared in “Journey Into Mystery,” No. 83, an image of which I have included below.
