Photo-Lettering’s Plywood in use for a science fiction anthology presumably edited by Robert Silverberg. Originally published in 1969 by Meredith Press, this is Dell’s paperback edition, first printed in August 1970. It contains a foreword by Arthur C. Clarke and three novellas; How It Was When the Past Went Away by Silverberg himself, The Eve of RUMOKO by Roger Zelazny, and We All Die Naked by James Blish. See Science Fiction Ruminations for a review by Joachim Boaz.
The condensed sans appears to be a phototype version of Helvetica schmalhalbfett, a style that originated at Haas as Commercial-Grotesk.
From the back:
Take a Fast Trip to Three Far-Out Worlds Of the Imagination!
A world in which the credit card is king, and debt has enslaved all humanity … a giant data bank controls the lives of every man and woman … land, air and water have reached the final disaster level of pollution …
The world of today? No, not yet. These are worlds of tomorrow, as envisioned by three great S-F names - Robert Silverberg, Roger Zelazny and James Blish – in mind-expanding novellas written especially for this volume.
