Comments: The last of a four part series. From the foreword, "Part IV of Master Slate Secrets completes the intended series on slates...The series does not cover all of the great ideas that have appear[sic] in print through the years as that would take a great deal more time, research and expense. However, the meat of all the great ideas of the art are here represented."
