19th Century German Theresienthal Hock Glass

Possibly designed by Henriette Steigerwald. The top of the stem is surrounded in rosettes and the glass bowl is hand painted with traditional Christmas tree and decorations of that period. It does not have a visible signature as such, but on closer inspection there looks to have been a mark which is now very faintly visible and looks to have been a painted on number. It’s in good condition but shows a little wear and tear and has a very small chip on the side of the base.
