My original tumblr post was here. This image was first posted on Tumblr by Scout’s Atomic Flash with a an original source at Flicr and the following explanatory text:

One eye viewed the room briefly before vanishing… – Startling Stories, April 1953. Illustration by Alex Schomburg for the story by Kendell Foster Crossen entitled, Halos, Inc. – a galactic parody about power and the powerful, religion and hierarchy, and the manipulation of the masses by corporate hucksters. All in the 31st century.

The ISFDB for the relevant issue of Startling Stories is here.
