Vintage Abstract Teal Lustreware Teapot

Funky abstract teal lustreware teapot. Super cool piece, with Star of David stamped on bottom with M in centre. I haven't had any luck finding any information on this piece or the stamp - super unique! Not without imperfections- crack in lid, discoloured spots - still a beautiful piece for display! Measures approx. 6" tall, 8.5" long including spout and handle.
