Buss Und Bettag Wir Haben Geoeffnet 3.html
This appears to be a webpage announcement that a business or institution remains open ("Wir haben geöffnet" = "We are open") on Buß- und Bettag (Day of Repentance and Prayer), a public holiday observed in Germany—mainly Saxony—on the Wednesday before the last Sunday of the church year. Since the HTML file itself wasn't provided, I can't confirm
