Birleen im Fruhling r.

Ok, found the plate.

This is German. The word groupings you first mention translate to:

"Birches in Spring"  "by" "Bert Pieck" (I couldn't easily make out the signature, so Bert Pieck could be slightly different, for example the P could be an S or an F.)

The Mark is "Nymphenburg" under a Crown and Shield with a diagonal field of diamonds.  This is the mark for Nymphenburg Porcelain of Bavaria and is the Wittelsbach coat of arms. 

Nymphenburg Porcelian was established in 1947 in Munich and is primarily noted for it's fine figurines. (a google search for "nymphenburg museum" will turn up a couple museums hosting these figurines.

They are in business today and can be found at www.nymphenburg.com and has the company history so I won't go into it here. (there is a language check box in the upper right of thier website to select whatever language you want to read it in!)

The plates also should have a couple other marks. a 3 or 4 digit model number and a 2 digit size number.

You would need to take it to be examined in person to know if the image is transferware or hand painted.  While the figurines appear to be in the triple digit values, the plates are significantly less. It depends on the quality (doesn't photograph well so I can't tell) if it's hand painted or a transfer copy, how many were produced, has it been used as a display piece or a functioning plate, etc.

Realize that plates in general are often worth much less than other products because they lay flat and are harder to display than something that stands up.

Hope that helps!
