Pulp Parade #119: Tube girl mystery

Pulp Parade #118: Hollyweird
Pulp Parade #120: Pulled toward the pit

I hadn’t intended to do to many covers of Thrilling Detective because generally it wasn’t very mad science, but this cover, from their September 1936 issue, has a tube girl of sorts. No cover artist recorded and the ISFDB sadly doesn’t index Thrilling Detective. I found this version of the cover at Pulp Covers. The version accessible through the Galactic Central index is smaller but shows somewhat less wear.
