A Lego leaflet from 1974 was posted on Reddit and immediately began trending on social media, as the content is as relevant today as it was 40 years ago. The letter reminds parents that the urge to create is equally strong in all children, boys and girls. It's a compelling statement to make for the 1970s and more importantly, it still holds true today.
Another Reddit user pointed out that it was consistent with their marketing of that era and didn't pigeonhole their products to just boys.
This is exactly the key to Lego's success. A few years ago, Lego nearly collapsed because they lost focus on the brick and instead introduced more gender-specific toys. Doing a complete turnaround to save the company, they went back to their core idea of unisex toys. Now Lego is more popular than ever and it looks like they are here to stay.
