Businesses have to get their books reviewed at least annually. In the fall of 1968 the Stockholm based cooperative the Milk Central (Mjölkcentralen) had their books reviewed by a chartered account in Gothenburg (Göteborg). The Milk Central was a cooperative owned by Swedish farmers, its successor Arla still exists and the Arla brand can now be found in quite many countries outside Sweden, Denmark and Finland.
The chartered account Mr. Ruhne was employed at a subsidiary to the Federation of Swedish Farmers (Lantmännens Riksförbund - LRF) and was responsible for the review. It seems like he was done with his work on Monday 21 October because then he sent back the books to Stockholm. Better safe than sorry he insured the package for a whooping 25,000 kr, close to $5,000 USD in those days.
The red label marked with a capital V for value marks that the item is insured. In 1968 the fee for insurance was 1.40 kr + 0.10 kr per 1.000 kr insured. It took only one day to get the parcel to Stockholm and two days later the parcel was picked up by the General Manager Mr. Pehrsson.
The stamp at the left is the 10 öre in the low denomination series New Numeral Type, the two others are typical parcel stamps: the 2.50 from the Three Crowns series and the 5 kr Royal Palace. Originally the 2.50 kr was used to cover the fee for parcels weighing between 3 and 5 kg from 1961 to until July 1964 when it instead covered the weight class 1 - 3 kg until July 1965.
