From an issue of the American Brewers Review later in the year, photos of the 1911 Second International Brewers Congress in Chicago.
The first is the main hall with its equipment displays, the second, a miniature American brewery, the third, a model in papier-mache of a German brewery c. 1800, and the last, the Banquet held in the Gold Room of the Congress Hotel. (Double-click for good resolution).
The sign of Union Fibre Co. is visible in the first. Union fibre is an industrial product, a combination of fibres to form brushes for cleaning. It is still used, see e.g., here.
