Interesting set of 6 albums of foreign countries, mainly Eur - Lot 19

Interesting set of 6 albums of foreign countries, mainly Europe and the USA. We start with 1 square album, beginning with Germany after 1945. We find the traditional series with zones A to S, the bizone (including the blocks), then West Germany (with the "Cor de Poste" series and the continuation of the first issues). Then we see Belgium from the first issues page, followed by the pre-war period (first Orval series) and the 1950s. Then we have the "catalog ends", followed by the first issues pages from the United States to the end of the album. The second album is devoted to Belgium, (from the first issues to the 1990s (including "catalog ends", P.A., Colis Postaux). The following 3 albums feature various European countries (Spain, Croatia, Norway...). Last but not least, there's 1 very nice theme on "Press and Printing" in an album of over 40 pages. Everything in each album is new and postmarked.
