Featured Possibly 20-30's Bauhaus/De Stijl geometric shapes decor plate set.

Hi guys!
Looks like my previous post was deleted for some reason
I have a lot of pieces to share, but I really need help with this beautiful set I found at German flea market.
It looks in Bauhaus, De Stijl or Constructivism style. I've been looking for the artist, but it's difficult without even knowing the production company, there is only XI/75 under the glaze. I'm new to this field, but from what I saw, the craquelure, weight and the base color, it looks 20-30s. But triangle shaped plates were popular in Germany in 50s, that's if it's German. Colors are also darker, not just primary colors, but Theo van Doesburg was using dark colors as well..
As for the sets of the plates, I only found one by El Lissitzky, but it has a different marking style and it's spray painted.

I found other plates online, but nothing with these marks. The widest part of the main plate is 24.5cm and small ones are around 9.5 in diameter.
I would really appreciate any info, thank you all in advance!

 

They look like they could be by one of the Russian Suprematist Avantgarde artists of the Vitebsk school, but as you said, Bauhaus and De Stijl are related styles.
I know Malevich designed porcelain plates that were manufactured by the former Imperial Porcelainfactory in St Petersburg/Petrograd. Those looked different from your plates, as do the El Lissitzky plates, but I wouldn't be surprised if other Suprematists designed porcelain as well.

Apparently Theo van Doesburg designed ceramics, just like he did glass design, but I can't find any that are actually by him. I imagine they would be decorative rather than utilitarian.

 

Thank you so much for your response!
I was thinking Russian, but it had to be produced in the early communist times, because the Suprematist plates I found online have a hammer and sickle mark.
The large plate of my set has 3 holes possibly for hanging or a stand, so it is 100% decorative. And it doesn't have any knife marks or signs of use. I can't imaging how the small ones should be displayed then..
I also found that Theo van Doesburg was calling his paintings "Composition" and a Greek numeral depending on work. So it might explain XI on the set. Or it might be just wishful thinking

 

Problem is that there is no factory mark

 

You're not the only one who hopes to own a Theo van Doesburg one day. He is my favourite of the De Stijl artists.

I hope one of the other members recognizes them. And sometimes the answer comes after a few years, when a new member indentifies a mystery item.

 

I love this set, so I have no problem to continue the research. I've a lot mystery pieces I'll be posting soon
Thank so much for been so nice and encouraging!

 

If you find the answer, will you let us know?

 

Sure! I'll keep you posted
