You need not open the door so frequently for the doctor if you would always use Sunlight Soap, Lifebuoy Soap ... / [Lever Brothers Ltd.].

Advertising leaflet for Lever Brothers' Sunlight laundry soap and Lifebuoy Soap (for house work) "destroys disease microbes which thrive so readily wherever dirt is found ... protection from infection.". The illustration initially shows an elaborate yellow doorframe set in a red brick wall. The green door has text on it and when it folds open a view of the hallway and scullery is seen inside with a maid on her knees cleaning the tiles and another doing the laundry.
