A Specter Is Haunting Texas - Fritz Leiber
CAD6.66
1978 DAW edition of this Leiber story originally published as a 3-part serial in Galaxy Science Fiction in 1968. Very cool H. R. Van Dongen cover artwork. Unfortunately I think another book was stuck to the back of this one some point in its life, as there is residue of paper on the rear cover (see photos) but it is in otherwise good shape.
