The cover typeface is a rare bird: Obliq was designed by Ellipsis and issued by Letraset in 1983/1984. The monolinear serif comes in two weights, both of which have been used here. Harold Lohner made a loose digital interpretation named Oblique Text (Harold’s Fonts, 2000). If you happen to have any information about Ellipsis, please let us know in a comment.
