Apparently, there was no #13. It was to have been printed in the winter of 1945. A few possible reasons for its not being published are WW2 ending, or Fox's trouble with bankruptcy at his company including his printing press company (if he did own it). The cover was printed at Central Printing Company in Pennsylvania, but never used.
