Sanctum Books
From 2006 through 2016, Sanctum Books republished all the pulp-era Doc Savage titles — plus The Red Spider. (The novel was shelved in 1948 and printed in 1975 by Bantam Books.) The Sanctum editions were usually two novels per volume and included original pulp artwork. (Unlike the Bantam reprints.) The Sanctum books also included articles by Will Murray and occasionally material that had been removed from the original manuscript by the pulp editor. The covers primarily utilized the original pulp art, but some issues were also published with variant Bantam covers.
The HTC offers a printable Sanctum Publication List that includes which volumes also had a variant James Bama cover.
