Burberry Authentic Patent Leather Vintage Rouched Check Nova Flats

Size 37. Very good condition though its kind of rubbed the numbers off but they still can be made out- by someone who can see. So these were extremely hard to find using any photo search out there…I found 2 that were already sold on Etsy, so I couldnt see much about them. I believe I found a pair sold on here. None was found on ebay or any other major platforms..even pintrest.
The ones that do show everywhere have a different color pattern, it has the white and lighter brown hues while these hack darker brown hues and black checked pattern.
I say vintage because of all the sold ones I found, it was written in the description or/and title. The rare comes from my own research and shouldnt be taken as factual in terms of trends/value.
I personally dont know how old they are. I only know they were worn a couple times, mostly indoors and they sat in the shoe closet, yeah..shoe CLOSET…boxed up for “quite some time” and forgotten about. Smoke pet free home. Reasonable offers plz.
