Architecture and design Facebook group banner

We already have a certain design, which you can just elaborate on or create a new one. We attach this design, but your proposal should be without a text or at least without "5 let". If you are creating something completely different, let us explain it a little bit, what is the reasonation behind it.

This banner is for a Facebook group, which focuses on Czech communist architecture. Our group "Ugly Architecture" holds ambiguousness in its name. We understand, that for most people, this architecture is ugly, and that is why we call it this way. But within the group we explain, how beautiful it is. And that's why we used two black stripes with one yellow as shown lower. That symbolizes a facade of a completely black house, which would many people consider ugly. But at the time of the construction, it was probably the color of elegance. That's why we added a yellow line, which has to represent gold, trying to indicate, that it is not so bad.

No text, please.
