Conceptual-Drawing-Joseph-Koncelik ???

I saw this book on Amazon. Does anyone know about it?

Conceptual Drawing by Joseph Koncelik

Thanks

I have a copy of it that i use with my students who need help in sketching. It is a great book and the DVD that comes with it allows the students to actually see the movements of sketching, which takes it above most sketching books.

Thanks for the info. It’s pricey and I hate to buy things without some info.

There are no reviews or anything online. I’d like to see sample pages but Amazon doesn’t have any.
