Faulty Pronoun Reference, Comparison and Punctuation of the Restrictive or Non-Restrictive Element

“I made several films while still in high school, one of which was called Faulty Pronoun Reference, Comparison and Punctuation of the Participle Phrase* (or something like that) and was about grammar. More specifically, it compared three commonly made grammatical mistakes with three people who were making them.The soundtrack was a dirty poem (what else?) and I made my own concrète sound. * ... Punctuation of the Restrictive and Non-Restrictive Element (?)” (George Landow, letter to Sheldon Renan, 1967) (Lost?)
