Cartel seat (monument)
Cartel seats as monuments were the headquarters or other premises of historical, no longer existing cartels in the sense of a group of cooperating, but rivaling enterprises. Often, these associations had been syndicate cartels being an advanced form of entrepreneurial combination because of their tight organization with a common sales agency. The cartel buildings had been used for secretariats, meeting rooms, sales offices, advertising agencies, research departments and further more. Many such historical buildings can still be found in Europe and the United States.
