Riser/AndromedaRiser/Cygnus

This page contains (all known) covers with "Riser" cachets, mostly on un-manned satellite launch or event covers.

Charles R. Riser of Bowie MD created Riser cachets to mark satellite launches and other space-related events. These covers include a Riser logo. The covers found in this page are primarily for un-manned satellite (or scientific rocket or balloon) launches or events. Covers for manned and other missions are included if they contain an element of interest to the authors.

Riser also manufactured covers with the following logos: Andromeda, Andromeda Space Covers, Andromeda Cover (numbered), and Cygnus Cover (numbered).

Nearly all Riser launch and event covers were produced on airmail envelopes.

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.
