In the area of Seoul known as Apgujeong, I found more mosaic murals in the subway station. These also use the grid style of making mosaics employing the 2 cm tile, but also a little bit of handmade tile.
I’m not sure who made these since I couldn’t find a plaque located nearby with any information on it. Apgujeong is a very upscale part of Seoul though. Boutique stores like Prada etc and fancy department stores… aswell as plenty of plastic surgeons! Funny how the two seem to go hand in hand these days… lol.
