1942 letter parcel (up to 1 kg) label, Narva-München
Posted from Narva to München, likely in 1942. The rate 90 rpf corresponds likely to heaviest letter class (501-1000 gr) 60rpf + registering 30rpf. There was also 90rpf parcel rate to Germany (up to 1 kg), but I’m not sure if such parcels were registered. Scarce.
