I had never seen works of this type before and I find them fabulous, because if I fix my gaze on a point, after a while my eyes begin to see them in 3D and I can see their depth without getting dizzy. It reminds me of when I trained my eyes for this type of vision years ago, and I love it.
In this work, I see the entrance to a crypt via stairs, mixed with the drawing of a large throne. Wow!

And in this one, I see a cemetery! It's fabulous! It's great that you were able to go to the exhibition and bring it back. It's something totally different and also difficult to do.

It's not very common and I can' say it for sure, but maybe I haven't seen it either.
It's so interesting to read what people see in those works.
Cemetery? @davideownzall sees a plaza here. 😂 This is getting funny.
🤣Oops... I still see a graveyard. How wonderful it is to see different things; art is brilliant!😍
Cemetery? I miss the graves here 🤣
