I purchase cardboard Do Not Disturb Signs when I see them at paper shows.Most of the ones I have accumulated were used between 1930 and 1960..It may have something to do with the fact that I was a travelling salesman for over fifty years and spent an average of two nights a week in a hotel or motel..
In any event these paper trips to another time are fun to look at ..
