As it is the path of nature for us to return to the ashes and dust whence we came, there’s always been something somewhat uncanny about the embalmed and thus non-decaying corpse. There should be no surprise, then, in seeing embalming taken up as a horror theme, creepy in itself and perhaps also something to throw in a bit of a necrophile or A.S.F.R. kink. The March 1936 cover painting by Tom Lovell and the story it illustrates goes to this directly.

At least Miss March 1936 has the appearance of being decently dead before being embalmed. I’m not so sure about the girl on November 1935 cover (issue ISFDB entry here).
While featured girl on May 1940 appears to be very much alive and putting up an active, if not exactly effective, resistance. Note that this cover might also be an example of the mummification trope, which I shall be covering a few posts from this one.
But perhaps the best or most shocking example (depending on your point of view) of the trope (as well as also the coffin stuffer trope) might be the November 1933 cover (issue ISFDB entry here), where the artist has managed, aside from some serious implied nudity, to get a look of real terror on the victim’s face.
And two-fisted hero/rescuer in sight, alas. Just the cold full moon looking on.
