The run’s blue thread starts here: a handbuilt rock cup, rust-brown and gritty below, wearing a milky blue-grey glaze band along its rim like frost on a stone lip. Four photos include the base, where “1973” is handwritten in black — a clean painted number where painted numbers belong.
Why does the blue matter? Watch it return on 1989 and 1990 — by the run’s end the milky-blue rim is a family signature. Piece 1973 of 10,000, listed at $19.73.
