Auction Series 257-264 in Zurich Day 5

1850/1980: Exciting and voluminous stock of postal history of several thousand letters, covers and cards from Germany, Europe and overseas. We noted German States, a collection of South American Airmails, among quantities of items that will benefit from close inspection. Just two items seen worthy of mention are a Prussian letter from Aachen to the Netherlands with manuscript Briefkasten, (letter box) insufficiently prepaid and taxed and a letter from Lambarene to Switzerland, with a senders mark "Hôpital du Dr. Schweitzer". rnrnrn
