Seriously, this book is just encouraging kids to keep junk. When George starts out to help clean up the neighborhood, he ends up deciding he wants to keep everything he found. When the man explains that a collection is one particular kind of thing, and asks George to choose one particular kind of thing to keep and to throw out the rest, George wants to keep it all, so he just arranges it all by color and and calls it a color collection. It’s still junk: a broken mug is still a broken mug, and a single high-heeled shoe still serves him no purpose, and it’s all still all over the living room floor of their apartment; but somehow we’re supposed to be impressed that he turned trash into something “beautiful”?
