This calligraphic text was included as a folded print in Portfolio Chopin. It is a linear extract of letters by Henri and Bernard to each other from 1962 - 1977. The two are identified by heavy printed letters, BH and HC. The maquette drawing for this print is also held by the Sackner Archive. The prints are stored in the Heidsieck drawer. -- Source of annotation: Marvin or Ruth Sackner.
