"Would you be so kind and go down stairs and see which key fits in the entrance. The key I gave to Johansson's in the shiny one. Bring back the key that fits. When you arrive I will go out at buy the paper"
On the back it's another note:
"Your laundry was dry so I took it in for you. If you want to, you can take the stairs today and go and visit Märta tomorrow if you get lonely. I'm going out to look for a cute fabric"
For me, this is the best part of buying old patterns, to find little treasures and get a glimpse in to the life of the previous owner.
