HJM printed border

(all known) covers with
"HJM"
cachets


This page contains (all known) covers with "HJM" cachets produced by Hans J. Mueller to mark satellite launches and other space-related events. Those covers include this "HJM" logo on the front lower-right. All but one of the covers listed below has an HJM printed border which depicts three satellites of interest to the authors, with the following detail images: "Explorer"-10 (upper-middle), "Mariner"-1/2 type (upper-left), and "Syncom" (left-side). (The authors' web pages for these three satellties are found here: Explorer, Mariner, and Syncom.) The HJM printed cachet is available in three colors: black, blue, and blue-green.

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

Two HJM covers have been found with a dark-blue printed border, different from all the other HJM cachets. Those covers, which were for submarine-related events, are marked with green highlighting. A few more covers with HJM submarine-related cachets may exist.

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.


Below is a list of "HJM" cachets on launch covers (including anniversary-of-launch covers, and launch-related event covers).
