I have three pieces of art pottery, it is marked weller pottery it is a half circle . The pieces are matt green with raised vines a while flower and three purple berries, there are 2 small candle holders about 3 inches tall and a matching piece that looks like a rock with a bunch of holes in it it also has vines and a white flower and 3 purple berries. The candle holders are not marked but the piece with the holes is, and I can tell all three match. Can anyone identify this pattern and how old they might be, and any value they might have . Thanks.
