A comedy zine with a catch: It's hidden on your subway commute.

WNYC News

If you want to get your hands on Public Transport Magazine, the clandestine self-published comedy zine, you’re going to have to take the New York City transit system.

And you'll have to look for the zine.

The magazine is the brainchild of comedian Al Mullen, who taps contributors for each issue, prints and staples thousands of copies at home and plants them across the transit system — inside subway billboards or across bus seats — as a sort of Easter egg for vigilant commuters.

Mullen said he’s left copies of the zine on subways, buses and Long Island Rail Road cars in Manhattan, Brooklyn and Queens. They've turned up in four boroughs, according to reports he's received from fans or via the “How’d you find it?” tip line on the magazine’s website.
