"TIP Galle" on a piece of glass indicates that it is a reproduction, not an authentic work by Émile Gallé. The word "TIP" is a Romanian term meaning "type," so "TIP Galle" means "Galle type". This mark was added to pieces made by Romanian manufacturers to indicate they were imitations or styles inspired by the original Gallé, helping to avoid legal issues with the Gallé name.
This is a decent example for its type with intricate flowers.
