My sister has this vase at her house. I don't think it is a reproduction. Please share your experience.
A 20th century reproduction in my view, an authentic Qianlong foot rim would have a worm back foot and the mark would be hand drawn and the decoration would be hand drawn, this looks printed to me, a close up photo of the decoration could verify this.
20-21st century reproduction to me. Looks too new. Sorry for the bad news!
