Hi Peter...I've been lurking and have enjoyed many of the discussions. I recently purchased several pieces from a family whose parent traveled the Orient in the 1950's, 60's and 70's. I am fully aware that my piece is not a priceless Chinese antique, but I'm hoping you could give me some information about it. I believe the mark is Quinlong. The mark is in blue under the glaze. The vase is decorated in raised enamels and is all hand painted. Quite well, I might add. I would appreciate any input.
