What is the marks?

Hello! I can't find who owns the marks on these. Maybe someone knows?

 

German or Austrian.

 

Thank you, I wonder what years?

 

I really like the decoration on these. So am commenting to bump this back up to the top of the list, in case anybody has an idea of age.

 

Huh. One of the impressed letters doesn't look like the English alphabet. I'm getting a bit of a folk design vibe in the decoration. Maybe Eastern European?

 

Thank's! I also had an idea that it was maybe Greece?

 

I found a similar cup and saucer on Wikipedia but I can't figure out who made it.

 

Thank you)
