The lot comprises:
1. Bavaria, 1888: 10-pfennig postal stationery card from Nuremberg to Stockholm, addressed to L. Schlesinger. The correspondence side features a printed balloon advertisement for the Nürnberger Bleistiftfabrik. The balloon is an advertising motif; no balloon carriage or Zeppelin connection is claimed.

2. Sweden, early 20th century: commercial envelope with printed Johansson & Åberg, Göteborg heading, addressed to Stockholm, with a red 10-öre Oscar II stamp and postal cancellations.

3. Finland, 1914: bilingual Finnish/Swedish cash-on-delivery address card, headed “Postiennakon osoitekortti / Postförskotts-Adresskort”, addressed to Helsingfors, with two adhesive stamps and postal markings.

4. Finland, 16 December 1936: Helsinki–Bromma first-flight envelope addressed to Paris, franked with a Finnish 2-mark stamp and bearing the blue Helsinki Aerodrome / Stockholm Bromma cachet.

5. Sweden, 16 December 1936: Bromma–Helsinki first-flight card with Swedish franking, a Christmas charity label and the corresponding blue flight cachet. Together, these two items illustrate the opposite directions of the same connection.

8. France, 1932: commercial airmail envelope from S. A. Sundin, Sivers & Co., Paris, to Lahti, Finland, with Sower and Pasteur stamps and a private “Par Avion” cachet. Included for its Finnish destination; not described as a first-flight cover.

9. Sweden–Finland, 1929: Stockholm–Åbo temporary-airmail cover addressed to Th. Allard, poste restante, Malm, franked with Swedish 10- and 5-öre stamps. With “Med tillfällig Luftpost Stockholm–Åbo” endorsement, “Trycksaker” marking, airmail label and red “Första turen” cachet. The accompanying album-page notes date this cover to 26 February 1929.

10. Sweden–Finland, 1929: Stockholm–Åbo temporary-airmail cover addressed to Hufvudstadsbladet in Helsingfors, franked with a Swedish 15-öre stamp. With handwritten route endorsement, airmail label, “Trycksaker” marking, red “Sista turen” cachet and a pictorial cachet referring to the temporary air service during difficult Baltic ice conditions. The album-page notes identify it with the final day of the service, 16 March 1929.
Items 9 and 10 are mounted together on the same album page and are offered in that mounted condition. Their individual photographs show details of the two covers; they are not two additional loose items.
Their reverses are not illustrated in the supplied photographs.

Total: ten postal items, two of which are mounted together on one album page, plus the original Barnens Ö greeting insert.
The insert is not counted as an eleventh postal item.

I can combine the shippings strictly following the Catawiki rules.
