Complex number and sign schemes are printed on each page. The basis for the images was probably letraset. The format differs from the earlier Gallery Number Ten edition in which Bory's name with the caption Arithmetic Text (1, 2, 3, ...) appears at the bottom of each sheet printed in red; the latter is absent in this edition and only 10 of the 18 sheets are present. This issue was edited by Brian Lane and Trevor Wells. -- Source of annotation: Marvin or Ruth Sackner.
