Jozefina Krosno. Jozefina Art Glass Factory (Krosno, Poland). This premium studio piece dates strictly to the late 20th Century (c. 1980s to early 1990s). The hand-drawn clear "wrythen" barley twist stem, distinctive trailing glass jellyfish tentacles, and the polished tool-work base rim are diagnostic features of Jozefina Krosno's iconic early export lines.
