Old reliquary from Bavarian farmhouse

An upper Bavarian reliquary from the late 18th or early 19th century. I have seen it today, when I photographed the Restorer Sophie Ziegler for a calendar of local tourist informations in the viallge of Fischbachau, Germany. The stain in the left upper corner is believed to be the blood of a saint, which has been in contact with this pencil drawing.
