NETHERLANDS EAST INDIES. 1901. Registered Netherlands Indies postal stationery envelope 10 on 15c violet upgraded with SG 85, 2 1/2c yellow (strip of four) tied by framed Maos hand-stamp in blue with hand-struck 'R' in blue, addressed to Nganjoek with arrival in violet on face. A wonderful combination. One of the most attractive covers I have had the pleasure to see.
