Next Monday, an ad campaign for atheism will begin a monthlong run in 12 New York City subway stations. The campaign features the slogan “A Million New Yorkers Are Good Without God. Are You?”

Forces behind the campaign remain mysterious, according to the New York Post. “The campaign is being coordinated by the umbrella organization Coalition of Reason,” the New York Post reported. “It cost $25,000 and was funded by an anonymous donor.”

Similar billboards were funded by the coalition in Dallas and West Virginia.
