I desperately need some guidance on identifying the maker of this little vase. Its heavy for its size, stands 10.5cms in height and has a polished out pontil on the base. My own research led me to believe that this could be either Kralik or Loetz. It has the look of an early 20th century art nouveaux piece. I am totally ignorant of this period of glass making. Has anyone got any ideas which would be much appreciated?
