So it would seem my grandparents stayed at a place in Hammer St, possibly the location of the dinner party photos, and possibly Paul and Elsie's place. I know the 4 of them travelled on a tour of Switzerland together beginning on 4 August 1952 and I guess by the 18th they had gone to separate destinations. The farewell party was on 20 September. I wonder how they knew each other, possibly through work as my grandfather worked for a Swiss company in Australia.
It's nice when things start to come together, isn't it?
The cards are addressed to
Mr & Mrs Smith b. Paul Weiss. "b." = bei = (in this case) c/o.
The cards are signed by
Paul & Elsy, so I would assume (can be dangerous, I know
) that this Paul is Paul Weiss and that the house in the Hammer Str. is the Weiss home. It sounds as though they (Paul & Elsy) are on holiday and have given the house to your grandparents for a while.
That would explain a) the address details and b) the bit about the napkins.
Interesting is that the cards are all written in the formal "Sie" form, not "per Du". Maybe they were indeed work colleagues or knew each other through work at least.
