Padded fencing master's breastplate with red heart for military fencing. Price without mask.

The heart on the breastplate isn't because the fencing master is in love, it's just that it's the most effective place to hit, because the "real" heart is right underneath.
When the fencing master gave a lesson, he encouraged his student to hit precisely this spot to get rid of his opponent as quickly as possible, in a real combat situation "at the risk of his life."
Slightly grayish appearance around the heart area, overall condition rather satisfactory. Turn of the 19th/20th century. Uncommon.
