This gloomy, sooty block would soon be remade for the Future. The big building on the right was not razed, but incorporated into the new building. Flayed and gutted, but it's still there today. See the gap on the right side of the postcard picture? That slender lacuna is the only testament to the old building's life as an independent structure.
The gloomy thing on the left seems to have been built in several phases as well; from the appearance of the facade and windows, it was used as a coal-pulverizing facility.
