I remember a book from my childhood with very detailed illustrations. The one that sticks out to me involves a junkyard with sort of a cutaway and you can see all of the creatures in their little junkyard world. In the same book, the protagonist (a young girl I think) visits the junkyard, which has a little house in it and I think she has tea there. That is about all I can remember. I’m now 25, for reference, and I remember reading it in the late 1990s/early 2000s. It’s not Junkyard Wonders or Paper Bag Princess.
Thanks, and can’t wait to re-read this book!
