This is a delightfully creepy find: Trimz DDT Children’s Room Wallpaper and Ceiling Paper.
Yes, Disney-themed DDT-impregnated wallpaper, advertised in Woman’s Day magazine back in 1947. Remember, it’s “Certified to be absolutely safe for home use.”
(Remember this next time you see such a statement being made!)
And no, I do not think this is a good idea.
