Bayerische Staatsbrauerei Weihenstephan, gegründet 1040. That's not a tax form, that's a year: Founded in the year 1040. That's what can happen if you make something real rather than (say) “complex financial instruments”. The company is still in business. The back of the coaster shows the Bavarian flag motif and the name of the "importer" who supplied this brand to the Frankfurt area (within Germany, Bavaria is like a country, kind of like how Texas is in the USA).
