Ads promoting atheism will be going up in New York City subway stations.

The monthlong ad campaign begins next Monday in a dozen Manhattan stations.

It features the slogan, "A Million New Yorkers Are Good Without God. Are You?"

The campaign is being coordinated by the umbrella organization Coalition of Reason. It cost $25,000 and was funded by an anonymous donor.

The coalition has placed similar billboards in the Dallas area and West Virginia. Another group ran ads in Chicago and in the Indiana cities of Bloomington and South Bend.

In July, another group, New York City Atheists, ran a similar but unrelated campaign on city buses.

One estimate puts the number of New York City atheists at about one million.
