Hello, Need some advise at this one.
I'ts very hard to figure out if an item is old, or made look as old.
This vase has no marks (what it even makes more difficult), Does an Antique item allways has a Mark?
I have read a lot of buying antiques (porcelain)and the things you have to take a close look, but it still is very difficult, can someone advise me on this one? and does anyone mean wat the charachters mean?
I guess it would be Peter:-).
Thanks again
