I'm such a sucker for thrift stores. And living in the San Fernando Valley there is an abundance of them. Much to the chagrin of my son, who'd rather be doing anything else.
Found this wonderful book yesterday at Goodwill. The Natural Way to Draw, "A working plan for art study" by Kimon Nicolaides. Published by Houghton Mifflin1941.
A mere $2.99 for an entire class on drawing by an instructor at the Art Students League in New York. I love that it has pencil marks on it's cover. I love that he includes very serious schedules for the student to follow. I love that it's called the Natural Way to Draw. So aptly named because his method for teaching asks the student to become so completely involved with observation, through all of their senses, that they will learn to draw from their own experience. Not through some magic formula they hope their teacher will convey to them. Sounds like he had his ego in check. Unfortunately, Mr. Nicolaides died before he saw it published. Luckily. he had a first draft finished. He must have been an excellent teacher. I'm so glad his "class" lives on.
