On the building of the former company headquarters there is an installation consisting of two lettering with single letters. The tubes probably glowed blue or white. The building is not directly accessible, but only visible from the Suedliche Uferstrasse or the Rheinhafenstrasse. The installation is defective and out of operation.
The former company building will be demolished; the fate of the neons is unknown.
Thanks to Georg Engist for the two photos!
