Writing this blog gives me a good excuse to troll around the internet for hours on end. One day I found this. Wallpaper that you can color in with a crayon. Not something you’d have seen in the 50s, of course, although by the 60s you started seeing wacky design concepts like this. And of course, the subject matter definitely has that retro feel. What fun! Reader Abby helps by providing this exact link. Thanks, Abby!
