Vintage Adolf Matura Vase, Two Abstract Modern Faces, 1970's Sklo Union Czech S

Breathtaking pressed glass face vase vase by Czech designer Adolf Matura, circa 1972. Is it one abstract face, or two faces kissing? The raised areas are polished to a satin finish. Measurements: 5 1/2" tall x 5 1/2" wide x 4" deep. Condition: Some wear to the finish consistent with the age of the piece. There is a miniscule rough "flea bite" in the edge on one side - see photo.
