This mark has been driving me crazy for two day’s because i kept thinking I have seen this mark before, then it hit me. After going over all countries of mark’s on web and internet. I think the mark is N for Norcrest. Some of their item’s are marked N but most is label’s which has a fancy N and label’s were square. They made ton’s of beautiful vase’s and figurines. A lot are collectables but rather cheap.All were made in Japan for american’s such as Enesco and Lefton. Even though you did not ask for value. Your vase is not worth much. I could be wrong but at least I tried. Also a lot of Norcrest items are numbered like your’s. Mostly !950,60,an70ties
