vintage Polish pottery Christmas tree candle luminary, little robins bird pattern

Tree only (no base) Polish pottery Christmas luminary candle holder, a tree with little robins numbered 453. (A Boleslawiec piece, I think?) This is 5 3/4" tall overall.

It's in excellent condition, nice and clean without damage or soot. You could easily use this without the under plate, especially with a battery 'candle'.
