There's this book that looks like it has some DeCarlo styled drawings in it
www.amazon.ca/Learn-Draw-Archi… Tho what I would suggest personally is a combination of common constructions forms (example, you pick the tutorial you prefer)
and observing DeCarlo's art:
www.amazon.com/Archie-Best-Dan…Try tracing the construction forms off of a DeCarlo drawing to get a feel of his characters and proportions at first (On a tablet or a light table or even a brightly lit window works!)
