The owners of Delaware News Co., one of the city’s last remaining old-school newsstands, are getting out of the business after more than a dozen years. Phil and Vincent DeFabis have put their business and their historic building along Delaware Street up for sale. The brothers are asking $415,000 for the 3-story, 3,000-square-foot building at 130 N. Delaware St., across from City Market. The structure was built in 1860 and now is home to a salsa-dancing studio and the newsstand. Delaware News could be included in the deal if a buyer was interested, Phil DeFabis said.
