Tome huitième.
A French book volume, marked Tome huitième, held by the Eisenbibliothek Schlatt, whose record gives no maker, date or readership. Its one picture is a dark geometric diagram of repeated wave curves drawn in white lines over lettered reference points, with dashed guide lines and a few marked angles. A designer might borrow its rhythmic sine-wave rhythm and its technical, chalkboard-like linework for patterns or backgrounds.
