Here's a retro ad back from Lego's 1981 ad featuring an adorable Lego loving little girl. She's all grown up now and she's a naturopathic doctor today. Also, she still loves Lego!

This is Rachel Giordano. The ad was shot when she was five years old and she was given a set of Lego to play with. Back then, there was no boys or girls toys specifically from Lego. It was just bricks for everyone! Giordano says:
[LEGO] were 'Universal Building Sets' and that's exactly what they were…for boys and girls. Toys are supposed to foster creativity. But nowadays, it seems that a lot more toys already have messages built into them before a child even opens the pink or blue package. In 1981, [LEGO] were simple and gender-neutral, and the creativity of the child produced the message. In 2014, it's the reverse: the toy delivers a message to the child, and this message is weirdly about gender.
