Unusually not a Ditko cover on this one, instead a nice reprise of a 1975 Charlton cover by Enrique Nieto. Ditko is represented inside with a trio of stories, one Traveler story from the 1950s, one meant for this title from the 1980s, but eventually published in an early SD Publishing book and a short bit from the PUBLIC SERVICE PACKAGE, plus a short essay.
There's also some (mostly) reprint material (which many people might not have seen before) by Robert Kanigher, Charles Nicholas, Gary Kato, Robin Snyder, Rodin Rodriguez, Henry Boltinoff, Joe Gill, Joshua Warren and Nieto, essays by Nick Caputo and Rodney Schroeter and a long letter column.
Not Ditko, but also of interest, the 13th book of SD Publishing's print-on-demand library is the first non-Ditkocentric one. HOW TO MAKE MONEY WRITING COMICS MAGAZINES 80th Anniversary Edition by Robert Kanigher is a new improved edition of the ground-breaking 1943 book by the legendary comics writer, creator of Sgt. Rock, Enemy Ace, The Haunted Tank, The Metal Men, The Flash (Barry Allen) and many more. This includes the full text of the hard-to-find original book with some visual improvements (including a copy of the Captain Marvel comics story that was included just as a script in the original). That takes up about 100 pages, there are more than 100 more, with a look at Kanigher's 1940s work, with spotlights and some full stories and rarities from various features. See over here for a more detailed look.As noted, it's print-on-demand, so available from various sellers, including Chapters/Indigo, Amazon and Barnes&Noble, should be spreading out to others.
