An 8-and-a-half foot tall letter "A," which stands for Atheist or Agnostic, erected by the Wisconsin-based Freedom From Religion Foundation, is on display at the annual Christmas market in Chicago's Daley Plaza on Dec. 12, 2013. Members of the group say it's meant to send a message that they believe that religious displays on public property are a violation of the separation of church and state. (Associated Press) **FILE**
