Original 70s Orange Tiles

M. found this is the front garden about a month ago. I found another two fragments in the side garden yesterday, where all sorts of rubbish is buried (more on which, anon). Will we find a complete tile?

I photographed the tile against the brickwork in the kitchen, which is where it probably came from. M. wants to replace the grey tiles behind the sink with some like this. Since that the kitchen has been made-over I am not sure we could use them in the kitchen without changing all the other tiles and some of the fittings too, but I adore the colour and want to find somewhere for them. Bathroom perhaps?

Of course, finding whole old tiles like this, or new tiles like this, is bound to be a challenge in itself, regardless of where we use them.
