Pulp Parade #285: Calmly move away from the giant ant

Pulp Parade #284: Serving her country
Pulp Parade #287: Erotic mad artist

This is Amazing Stories for November 1958, cover by Edward Valigursky. The ISFDB entry for this issue is here. I found this version of the cover at Pulp Covers, where the curator comments “I have to say, she looks less terrified than I would be in that situation.” You can download and read this issue at the Internet Archive.
