The 3 tiles today have some age to them. It was when I first started to produce them. I made ceramic frames for them and all was glued to a board. The public didn't like the weight of it. I didn't like educating the public to how much weight a wall will take. Thus, I eliminated the  framing tiles and produced only the main subject tile. Note that I did attempt to tone down the 'white' grout by staining it to compliment the tile color.
