Ancient Boïte for egg-shaped treats in hand-painted silk

Old and rare box, made of cardboard, covered with hand-painted silk on one side, with floral motifs. In the form of "easter egg". Could have once served as a candy box during the easter holidays Box found at grandparents' house (born in 1888) in an old trunk (with other old decorative objects). No confectioner brand. I had placed this box in a curiosity cabinet but I want to change my decoration.
