Lego sent us an email confirming the message's authenticity. "Yes, the text is from 1974 and was a part of a pamphlet showing a variety of LEGO doll house products targeted to girls aged four and up from the 1970s," said spokesperson Roar Rude Trangbæk, who added that the text remains relevant to this day across every LEGO product.
