This is one of the first uses of Milton Glaser’s Glaser Stencil typeface, which was released in 1969. In his 1973 book Milton Glaser: Graphic Design, Glaser calls it “Neo-Futura”. Art direction: Harris Lewine. I especially like what he did with the exclam on the title page.
Note the irony: The year after this book was published, the author, Clifford Irving (1930–2017) concocted a scheme to publish a fake autobiography of the famously reclusive and paranoid billionaire Howard Hughes. Irving lied to his publisher, McGraw-Hill, saying that Hughes had told him he admired this book — which is about an art forger.
The plot unraveled, and in 1972 Irving pleaded guilty to “conspiracy to defraud”. After conviction, he spent 16 months in prison.
