It the became a “thing” where it was the first book we got for every kid born in my extended family, and now that I have my own kids 40+ years later it was the first I got for them too. They both know it by rote, have the toys, had the bed sheets, everything. They’re now in the early years of school and still absolutely love the story and have the posters in their rooms despite them being “old” for it.
RIP Eric. You’ve left an amazing mark on the world.
