How to Draw Comics the Marvel Way

This book has become legendary in the art world, but I'm curious about what motivated Lee to share his techniques so openly. Did he want to pass on a specific message or nurture a new generation of creators?

I expected a lot of technical jargon, but the instructions felt really approachable. Has anyone tried to follow along and how did it work for them?

The book clearly promotes Marvel's aesthetic, but does that limit creative experimentation or inspire new artists to develop their own style?
