The Commission on Chicago Landmarks' permit review committee approved a plan that would allow the Chicago Cubs to install a new advertising sign above the right-field bleachers.
The electronic sign, which would measure about 75 feet, would display advertising and information about the game.
But the plan is not a done deal.
Ald. Tom Tunney (44th), whose ward includes Wrigley Field, wants the full City Council to approve the sign before the Cubs can install it, reported the Sun-Times.
Such an ordinance would ensure that the city and Cubs agree on a set of rules for other advertising at Wrigley Field in the future.
The Cubs did not comment on Tunney's proposal.
