This is a calendar advertising Koninklijke Paketvaart Maatschappij, which was a Dutch shipping line operating from 1888 to 1966. They had routes all around the world, Hong Kong, Brisbane, Cape Town, lots of others. They were also heavily involved in the allied war effort during WW-II, building troop ships, hospital ships, and others. There were mergers in the 60s, and today they have been folded into Maersk.

For all I would know, this could be a household name throughout Europe, but I don’t think it is very well known on this side of the pond.
