I bought a flow blue serving plate and found a green mark on the bottome shows "W & E Corn England Porclaine Royale". I did some searching online about this company's marks and found a same one as mine but only the word of "Porcelaine" is different. I think mine (Porclaine) is misspelled (missing a "e" in "Porcelaine"). I am not sure if this item I bought is a fake piece or not?? I can see the craze in the glaze on the bottom of the plate, that means it's an old piece, right?
