This photo has been circulating on the Internet since at least 2013, when someone first sent it to me, along with the caption, "Before girls were told that every single last thing in their life must be pink."
But it's not just about the pink. It's about... Well, this is the way I was able to dress when I was 7 years old. Blithely... No. Blithe. "Blithe to my gender." What I had of one at the time.
It is not possible for an ad like this to be produced today.
Note also that the little girl (or the marketer) did not believe she needed a kit to decide for her what she should build.
