Vintage Transylvania wall hanging identification

Hi,
I purchased this saxon wall hanging in Viscri, Transylvania about 20 years ago. It is prewar peasent craft, but I dont know what it is called or where a market would be to sell it. Can someone tell me what these are called?

it's written in German

A house guarded by the Lord God

Thank you for that wiki page, its so interesting!
I contacted the Cluj-Napoca ethnographic museum and they stated that these hangings were produced in the years of Saxon settlement in Transylvania from middle ages right through to fall of the Eastern block. I think this one is definitely late 19th or early 20 century.
Can anyone suggest textile collectors who may be interested? It needs to be in a good collection, not in Australia where I am.
