The HC is the inscription on the lithographic works of Jean-Paul Riopelle meaning non-commercial ( hors commerce). The prints of Jean-Paul Riopelle were, for the great majority, published on a number of 75. However, a few more were created and not intended for sale. These non-commercial works were intended to be offered to collaborators of his edition. These collaborators could be master engravers or people close to the artist’s entourage.

In 1972, he created the series called Les Suites. These are 17 large lithographs in white and black on Arches paper. These 160 x 117 cm prints were the largest ever made in Europe at the time.
