Yes, you read that right. The suggestion that a pretty girl is facing imminent transformation into some sort of snake creature. It seems like a somehow overly-specific trope to which to which to devote two different covers over a little over four years, but there it is. Maybe ophidiophilia was in back in the 1940s. A comparatively chaste if suggestive cover from July 1944.
And of course, a considerably more batshit (but loveable) one from October 1940.
Hssss…
The double-fanged hypo is interesting.
