Some more info: The clock is indeed glued-on cardstock. We chose cardstock for sturdiness, but in retrospect I’d recommend heavy-ish paper instead because I think it’ll flex better against the cardstock cover.
We go for that sort of bold, simple cover design in part so it can work when seen from across the room or as a tiny thumbnail on a screen.
The cover was drawn by Anne Thalheimer based on a design by me (which, as with all our anthology covers now, was based on a prior anthology cover designed by Anne, Dan, Marek Bennett, and me). The table of contents and back cover were designed and created by Matt Young. And keen-eyed viewers will note our eminent reviewer’s name among the contributors ;)
