vase was a wedding gift in 1923
Martha, it is a very unusual vase and I think you should take it to a good museum or auctioneer to get it checked. Most but not all early 20th century American wares carried a mark and the date is within a period of transition in terms of art forms. None of my reference books have anything quite like it.
If you cannot get to an expert yourself then try emailing one of the bigger museums. I can see that some of the applied decoration has been knocked but don't be tempted to get it restored until you have more information.
It could be that the vase is not particularly valuable but you are very lucky to have inherited such an attractive piece. Do let us know how you get on.
