Technic is Fun - Preparatory Book - 1969

Vintage 48 page beginner instruction book compiled, edited and arranged by David Hirschberg. Originally printed in 1948, this copy, I believe is from 1969. Some of the compositions are from Bertini, Duvernoy, Kohler, Spindler and more. The cover shows just a little wear and there are pencil notations inside. Overall, condition is very good.
