Here's a fun little side story from my tapestry trip to Milwaukee.
We stayed at the Knickerbocker Hotel. It was built in the late 1920's as a residential hotel. They had a mini-town square on the first floor, including shops, a beauty salon, and a grocery store. (I always read all the little booklets in hotel rooms.)
Have any of you ever seen a door like this one? Here it is closed.
Here is the door-within-a-door, open.
Here's the informative sticker, explaining how the door works.
And here's the hallway view. You can see the two locks.
This surely is a nostalgic peek into a past era! If you look back at the open door photo above, you can see, on the left, a little sleeve holder so nothing gets caught or stuck during the closings and openings. So thoughtful and secure!
