Tearing up old art

We were looking for an old poster for Dave the other day and I was aghast by how much space I was tying up storing my materials from my printmaking class from 1992, multiple copies of work that I would never even give away. This weekend I tore up most of it into 2.5x3.5" pieces so that Margaret can use it as artist trading card blanks (my work is only on one side).
