As an observer of interesting things, I have seen a tile that was mostly used on very old (50's, 60's) tile installations, mostly in bathrooms. Where a row of horizontal bullnosed wall tiles meets a row of vertical bullnosed tiles, the tile in the corner sometimes had a little tiny bullnose on the intersecting corner. I know that this tile was factory made and not filed off in the field, because the little bullnose "notch" is glazed. Question is... what is this particular tile with the little bullnose on one corner called? I drew a quick pic for clarity.
