This 1959 ad for an airplane toy throws in girls as an afterthought in the final seconds (“Every boy wants a RemCo toy… and so do girls”). It’s easy to dismiss the ad as quaint and representative of a different time, but today’s advertising seems equally gendered, with girls thrown in as an afterthought (like in this dinosaur toy website) or neatly segregated (see here, here, and here).
