The Chamber's efforts to diversify the local economy after the decline of coal are presented as a model for other communities. The building is locally significant under Criterion A.","narrative":"Built in 1926 at the corner of Mulberry Street and North Washington Avenue, directly across from Scranton's City Hall, this four-story limestone office building was designed in the Art Deco style by Edward Langley. It housed the Scranton Chamber of Commerce's regional offices, meeting rooms, and a ceremonial lounge, along with rental offices and storefronts. Its decorative features include limestone spandrels, a balcony over the Mulberry Street entrance, and marble and bronze interior finishes. The building is significant for its association with the Chamber's economic development work. Between 1945 and 1961, the Chamber organized the Scranton Plan, formed SLIBCO and LIFE, and built industrial parks that brought new employers and jobs to the region. The nomination credits these efforts with reviving the local economy after the decline of the coal industry.","period_of_significance":"1926-1961","architect_builder":"Edward Langley (architect); David H.
