I was visiting a friend, stopped by his office, and found a graphite lithograph sitting on the floor. It was framed, but the glass was broken. He saved it from his father’s estate. I made such a fuss about it, he gave it to me.
Below it is a piece of CP-1 Graphite set in an acrylic block. These came from different owners, but were all components of a gift set awarded to accomplished Argonne National Lab employees upon retirement. The gift set also included several post cards and envelopes, as well as a pencil, whose graphite, as you might have guessed, also came from CP-1 moderator.
