I sent a message to Hans Peter Koennecke asking if I could display pictures from his Master Roofer’s School held in Cologne, Germany. A group of skilled craftsmen gather and produce slate art which is incredible due to the detail and time involved.
More pictures are found on Hans’ Facebook page which I’ve linked above. Other teachers of the school include Uwe Bierbaum and Puma Kater. I apologize ahead of time for the titles that I’m giving the most literal meanings to.
