I bet it ends with his wife actually turned into that creature. Such classic art!
Now I gotta go back and look at it again--yeah, I think it's either that, or the creature is their child
My first exposure to these EC artists was way back in the 60's with a paperback called Tales of the Incredible. It had a story I believe with a similar ending, so very different than the DC/Marvel I was reading.
Beautiful little PB....I have a mint copy I will try to post from soon
