I have 2 sets of tea cups with saucers that were handed down to me by my grandmother and grandfather. My grandmother is from Montreal, Quebec and my grandfather is from upstate, NY. I know they traveled a lot but if they are from 1904-1927 my grandparents would have been children when these were made. I did some research online and found a web site that has the mark listed http://www.porcelainmarksandmore.com/silesia/waldenburg_1/00.php the particular mark that is on my set is image either 1-22 or 1-23 I cant tell if the color is blue or green, I think its green. Other than this web site, I cant find any other info or items that are for sale with this mark. I don't really know what exactly I have, so I would just like to know more about the pieces...
