Art Nouveau pocelain demitasse and plate unmarked, but is Beyer and Bock

Some time ago we bought a tea cup with its saucer “fully” unmarked (first picture). They were pure “art nouveau”. I cannot remember exactly to whom we bought it, I think to Olga at the beginning of 2013. The daisies of the cup have white accents in the petals and gilt jewels over the yellow of the center (second picture). I looked in internet selecting porcelain from Bavaria since from the color and texture of the porcelain I guessed it was from there. On November I found a second saucer without cup in another shop. I bought it because it was marked. They are identical, see next picture. It was found to be Beyer and Bock from Volksted (Beyer & Bock (1890 - 1960).http://www.porzellankompass.de/module-Pagesetter-viewpub-tid-2-pid-134-lang-de.html
