Beer In Ads #1057: Party With Mathäser-Bräu December 31, 2013 By Jay Brooks Tuesday’s ad is for Mathäser-Bräu, from 1928, a Berlin brewery and the operator of the city’s largest beer hall in their heyday. They were bought by Löwenbräu in 1907. It looks like it must have one decadent New Year’s Eve party.
