The poster is printed on canvas and is 32 in. wide X 39 in. long. It was frequently but carefully handled, and is in good condition. It has minor ware on the bottom which is shown in the photos.

It depicts a blast furnace, which is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.

The fuel (coke, ores, and flux (limestone)) are supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and flue gases exiting from the top of the furnace. The downward flow of the ore and flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process

This poster had been used as the science department of a German school in Ludwigshafen am Rhein.

This is truly authentic, historic, and had an important function in Germany’s education system. And it is a GREAT souvenir.

The German Reichbanknote, a part of Germany history and a popular collector's item, is dated 21 April 1910.
