This square of linoleum was on top of *another* square of linoleum by the front door. The black curve is where the rug used to end; they had a metal edging there. When we pulled up the carpet, one corner of the yellow stuff was visible under the brown. That was pulled up a bit further, as you can see in the picture, by one of the guys who came to give us an estimate on the refinishing. (It's all gone now, though.)
