This page contains (all known) covers with "Space Master" numbered cachets produced by Robert G. Rank of Union City NJ to mark satellite launches and other space-related events. Those covers most often include this logo and this logo or this logo on the front, and are often numbered either on the front or the back. One cover (with "Space-Master A" on the back) has been found that pre-dates Space Master no.1, but the authors have never seen covers numbered 12 or greater. Covers with those numbers may not exist.

Blue highlighting is used to identify postal items only of interest for completing this collection of numbered covers, as they are not in the domains of primary interest for the authors.

Readers who know of additional information or images are invited to contact the authors using the e-mail addresses found at the link at the bottom of this page.
