This paperback edition was published by Harlequin in 1962, with Bern Smith’s cover art depicting a fiddling ghost rider followed by a crow.
The interlocking yellow caps appear to be from Toronado Interlock (or a precursor?). With the exception of the S and a few stroke endings (which might have been modified, or available in alternates), they match a showing in a 1969 Lettergraphics specimen. See Troubled PB for a digital interpretation.
