75-gram UPU-rate registered cover
to Amsterdam, Holland
60-80 gram = 1.25 Fr
Registry fee = 50c
The 87 1/2c Marie-Adélaïde definitive was issued to pay the 5-kg parcel rate to Germany. Consequently, we do not see this stamp used on correctly rated covers. But here it is correctly used as a pair on a 1.75 Fr. fourth-step, registered UPU-rate cover. I don’t expect to see another.
