City Club upper stories http://farm3.static.flickr.com/2409/223 6134044_6e5831424a.jpg?v=0 This postcard shows the upper stories of the City Club Building, dedicated in 1924. Algonite was a cast stone manufactured in St. Louis. The St. Louis Building Arts Foundation also has one of the Algonite Stone Manufacturing Company's scrapbooks showing original models. Like all of our materials, the scrapbook and this postcard are in temporary storage awaiting the completion of our new library at our future Conservatory facility.
