Hi all...........I believe your Jack in a pulpit glass is true Murano glass made some time after WWII up to as late as the 60's sold mostly in larger down town department stores. In the Great Lakes area, where I live, most of the Murano glass was FT,AVEM, and alot of generic small glass house stuff. I think there is a good possability that your glass is FT. And yes, alot of people remove the labels because there is more money in American art glass! I hope these pictures help!.....................Jerry
