So this a photo I took back at the Vienna Central Cemetary on All Saints Day.
It says 'Kontner: Yard Work and Grave Cleaning' and it has a picture of a gleaming grave.
These things were all over the cemetary. Kind of how like in the US landscapers or contractors will put signs up on your lawn when they are working on stuff to advertize, here they do the same thing except with graves. I just like the idea of people walking around and saying 'what a lovely grave, honey? I wish our grave would be clean like that! Let's hire Kontner to do our grave cleaning!."
