Probably acid stained glass decorated by Ilanit of Israel using a factory blank from France or Italy. Similar things are made in Israel. (Info from Ivo on previous posts)
They are pretty things. Did a quick search for "Ilanit Israel" and all I found was a singer.....added "glass" to it and found a link to an ebay item with its original lable stating "Hand Painted by Ilanit Glass, Olamtov Jerusalem"
Edit - Not sure how the blue vase images got added to my reply
Mod: They have gone away now
