Yambol's Museum Statue - A Thoughful Woman

Another day another statue outside Yambol Regional Historic Museum. This is another female deep in thought. By the style of the dress she is wearing it looks like a village woman, perhaps waiting for her husband who is out working in the fields. She looks worried and pensive, then I noticed there is am incaved heart shape on her chest. It's all a bit too mysterious to me right now. Perhaps answers might be in the museum if make a point of going in.
