Roll and pinch

One way the ancestral pueblo people would contruct pottery would be to roll the clay into long round strips.  The strips would be laid and wrapped in a circular motion wrapping each layer on top of the one below.  The round strips would then be pinched to flatten and mesh together.  If you look close at this piece you can see fingerprints.  Just imagine who did this?  How long ago?  How did they use the pottery?
