I was a parent Of two boys during that chapter and marinating in kids. I remember I got turned down by LEGO when I first went to them for a license to do a book but the boys told me not to take no for an answer. We ended up doing a deal because I pretty much had to. Btw, when Klutz was only about ten minutes old, I got a note from a scientist describing a little book he’d written on how to solve a new puzzle that was just getting traction. I turned it down because I figured any puzzle that was so hard people needed a book to solve it would never take off. His book sold 8 million copies later that year when he sold it to a big NY publisher. I’m still not sure where my logic went wrong. Does anybody still have a copy? The Simple Solution to the Rubik’s Cube by J. Nourse?
