I apologize, there was a bit of a glitch with the site and I was not able to see your question until today.
Your set was made by Kalk Porcelain Factory (Geyer and Koerbitz and Co) of Thuringia, Germany. The PKE represents Porzellan Kalk, a factory that specialized in tableware, tea sets, figurines and vases.
The set was made in the late 1930's. The value of your set (which does not have a pattern name) is $300.00.
Please do click the stars to rate me, thank you!
