Stock Photo - April 23, 2020, Berlin, Berlin, Germany: Italian hatter GIUSEPPE TELLA can be ssen waering a face masks behind a sewing machine in his studio in Berlin. Tella and his partner ALEX VON DUNGEN produce individual, elaborate hat fashion from high-quality materials. In the the course of the worldwide Covid-19 pandemic they have expanded their production to include face masks. From April, 27 people in Berlin have to wear a face mask in city buses, subway and underground trains. Also in the partly reopened retail sector and in contact with persons at risk, such protection is only strongly recommended. As there is still a lack of respiratory masks and protective equipment among doctors and hospitals, many entrepreneurs offer self-made, non-medical masks for sale.
