Sweden, Postal dokumentation collection 1850s–1950s. Valeurs a recouvrer envelope, form No. 21 (1880) unused, recouvrement lists cancelled HARADS, rate tables, e.g. form Nos. 521 and 522, early receipts for registered mail sent to abroad, e.g. to Germany in 1859, complaints, etc. Looks interesting.
