Help evaluate the vase and a pair of plates
 

Vase about 80 cm tall. Plates of about 38 cm in diameter. One with a crack on the edge.

Please photo stamps vases, if any.

In the first photo. Others were found.

At the Viennese brand like, but also on "pseudo-Vienna", too.
Stamp on the plates could not tell.

On a plate stamps inscription SCHUTZ BLANSKO ... German?

Now Czech, Olomouc (cool city!), And when the Czech Republic until 1918 was a city of Austria-Hungary, the Austrian. :)

I understand that, depending on the year and the price ... :) Tell me, how you can get all this good year accurate?
