Well, this is something, I really remember very well (especially, since it's just three miles away from here
):
a 'collective' house [of course that not the official name]:
on the left, upper part of the postcard, you see the complete house and partly the coal shop, besides on the right is the ballroom [dancing lessons took place here!], which was used as theater room as well.
The pub is to be seen on the left, the store [called "colonial wares shop"] on the right.
In my hometown, about a dozen pubs had shops in another room. Our coal merchant only had a pub, but additionally two guestrooms (b&b).
