We had in our house black and white floor tiles which the previous owner installed. They are large tiles - about 45 x 45 cm and about 3 mm thick. They are an LVT glue down as far as I can tell. I'm trying to identify what brand they were as there is no makers mark or logo on any of the tiles. They were laid in a black and white checkerboard pattern, and have a distinctive imprint on them which looks like a kind of woven knot. Any ideas anyone? Have tried reverse google searching in vain. Photo attached which has been doctored a bit to show the pattern.
