It is the rule in pulp: no one and nothing is more interesting to a bizarre creature than a comely female human, and this cover by of the February 1940 Fantastic Adventures by Robert Fuqua (1905-1959) exemplifies the rule. I think it is probably illustrating Bertrand L. Shurtleff’s story “New York Fights the Termanites,”, although an interior an interior illustration by Julian S. Krupa (1913-1989) suggests a different conception of the beasties.

It looks like a pretty normal rush-hour on the 6 train to me.
