Thank you for submitting your item for appraisal. This appears to be the Miro lithograph in colous Series I, Red and Green, 1961 . Another "h.c." print sold for approximately 2000 USD not long ago in a well advertised auction. A print from the edition of 75 sold at auction eleven years ago for approximately 5000 USD. "hors commerce" or "before business" prints were originially intended to serve as a printing guide for the printer. Today such impressions are pulled outside the regular edition for the use by the publishers and are regarded to be of lesser value.
