neatly mounted on homemade pages, better including (unused) PR19 (crease), PR57-64, PR67, PR71-72, PR74, PR71-79, PR81-89, PR90-92, PR102-06, and PR114-25, used PR24-25, and more, few certificates, regummed/reperforated stamps and small faults to be expected but certainly some original gum, fine to very fine appearance, a wonderful group for continuation or resale
