Antique Wooden German Catholic Prayer Box With Wax Doll Holding Cross

I have obtained this antique wooden german catholic prayer box.  The wooden box has a sliding lid.  When the lid is removed, there is a piece of glass protecting a tiny wax doll holding a wooden cross.  The back of the box lid has a paper attached with german text that I am assuming is a prayer.  I have researched many sites trying to find a similar item to compare and obtain a general value.  I have been unable to find anything even close and am becoming frustrated.  Can you help?
