Hi, I agree with both comments, this is most definitely a vase retailed in TK Maxx a number of years ago, I bought several from there! I buy decorative ware from T K Maxx and Ikea to dress property for my cousin, so I recognise there goods very well LOL! I also agree that dirt and grime are certainly no indicator of age, just the environment it has been kept in. If you love your piece that's all that ever matters, I have a few pieces that have very little commercial value but I wouldn't part with them at any price!
Warmest Wishes,
John
