I can't really describe much about them that I haven't already described. They appear to be some sort of ceramic that has a milky glaze that is crackled on a few pieces. The design on the pieces is black lattice sort of border with blue circles in between lattice. The only thing I can find when I google Lucie made in Germany pottery is about Lucie Ries, a prominent pottery artist. This doesn't look like her other work, and appears to be mass produced. However, Lucie Ries did work in a Vienniese or German ceramic factory early in her life.
