Pulp Parade #329: That’s…entertainment?

Pulp Parade #328: An earth-shattering ka-boom
Pulp Parade #330: Tube girl oh yeah...and some more dubious stuff

This is the cover for Marvel Science Stories for November 1938, cover by Frank R. Paul. The ISFDB entry for this issue is here. I found this version of the cover at Pulp Covers, the curators of which have also made the entire issue available for download. As an example of this issue’s interior art, this illustration to Henry Kuttner’s cover story “The Time Trap,” also by Frank R. Paul.
