Gotham’s gone gingerbread. Self-appointed Big Apple gingerbread man, Jon Lovtich of Queens, has erected another decadent Yuletide display for the tradition’s 30th anniversary — and it’s the first time his record-breaking exhibit pays homage to the city he calls home. Lovitch, the creative mind behind the Gingerbread Lane exhibit once displayed at Chelsea Market, found a new home for his candy community at The Shops at Columbus Circle this year — which inspired him to drum up more fanfare surrounding New York during Christmastime, he told The Post.
