The Pittsburgh Downtown Partnership today will begin installing the first of more than 30 graphic "makeovers" to vacant Downtown storefronts to improve their appearance for the G-20 economic summit.

The first storefronts to be treated are at 925 and 927 Penn Ave., a short distance from the David L. Lawrence Convention Center, where the Sept. 24-25 summit will be centered.

The partnership said seven images have been developed to depict the strengths of Pittsburgh and will remain in place after the summit.
