Apparently there is not just a market for (old) postage stamps, but even for old envelops without content. I didn’t find it myself, but on Ebay (1) appeared an envelop addressed to Farwerck.
“Groot Badhuis” (‘large bathing house’) was a hotel that was built between 1926 and 1928. The fishing village aimed at tourists and started to become the coastal place that it is today. The hotel was enlarged a few times and demolished during World War II, when the German occupiers tore down half of Zandvoort to build coastal defences.
If you receive a letter at a hotel, I suppose you are known to stay there for larger periods of time. It is sometimes said that Franz Farwerck spent the summers in Amsterdam at the place of his brother and that his brother spent the winters at Franz’ place. This envelop suggests that Farwerck went another 35 kilometers Westward to also spent time at the Dutch coast.
There are a few more things to think about concerning this envelope.
The description of the Ebay lot is: “Cover Postal stationery Netherlands Indies, 1926. Makassar to Hilversum.”
Farwerck had contacts in the Dutch Indies. This is not too strange, because in that period more than a few Dutch people moved to the colonies. Lodges of the organisation that Farwerck headed were founded in the Dutch Indies from 1911 on. From 1919 the Dutch Indies became a federation of its own.
1926. Farwerck had been head of the Dutch federation of Le Droit Humain since 1923. He was in a productive period of writing, founding lodges abroad, etc.
The National Socialist Movement would only be founded in 1931 (and very popular in Zandvoort 1942), so the most likely suggestion is that this letter came from Farwerck’s Masonic circle, but not from a lodge that fell under his command.
