Oh, I saw this fucking book when I was trolling Amazon for alphabet books for our daughter. The author also wrote ABCs for Girls, in which he reused basically the same picture of an elephant but the elephant is playing with a girly-colored ball and doesn't have tusks. I shit ye not.
Pointlessly gendered ABC books for kids.
Girl's book is pink and features letter examples like, "F is for Flower" and "T is for Tea Set"
Boy's book is blue featuring letter examples such as "A is for Airplane" and "B is for Bulldozer"
It's never too early to divide the language and start learning those gender roles!
