Kinga says this is “The first and lost version of Matisse's linocut from his pre-psychedelic period.”
This card is a print from a single block. Some of the cards, including this one, appear to have been inked with a brayer, and some with several colors of stamp dabber. The colors vary greatly from one print to another. I scanned the one that seemed the most pre-psychedelic. On off-white cardstock with flecks of blues and violets.
