Runner? Wall panel? Glory to grungy

From a real deal high end antiques estate. The grungiest thing I could find there. Formerly quite glorious I’d think. They liked French things. The closest I found to this in a google image search was French 18th century. I have zero confidence this is similar in origin but just a possible starting point. Photos are really bad for some reason. I don’t recall exact length but probably like 35-40”. Wondering the normal where/when/whatnot….

 

The fabrics look old, but I have no idea when they were sewn together. The brocade on the back does look French and old.

 

I think its Victorian with some much older fabric used .
