Unmarked, but I believe this is a Michael Andersen and Son’s vase. About 3” tall. The bottom has a couple lines that could be a bit of a signature , but it could also just be marks from the production process- I really could not tell. The finish and pewter flowers are typical of Andersen pieces. There are some flaws in the glazing and along on the bottom edge, which I believe are from the production process, not damage. Please see all the photos as they are the best representation of the items appearance and condition and show these areas. Feel free to ask questions or request more pics.
