Hi, I have been trying to find the maker of this porcelain plaque/tile? and its value. It is in a frame with a 3 dimensional male and female in white and the flat part is pink in color. It has an impressed number 728 and a blue number 4, the mark is F.W. and has a crown? hanging from the top of the F. Can anyone tell me who made this & how old it is? thanks [img size=124]https://kovels.com/media/kunena/attachments/legacy/images/P1010004-64b5ff678b90022e0fb362db48e3a9e7.JPG[/img]
