Whitney cachet

This page contains (selected) covers with Robert B. "Bob" Whitney cachets, mostly on un-manned satellite (or scientific rocket) launch, anniversary, or event covers. These (~170) covers, which do not include a logo, were produced from 1967 thru 1990 (23 years), most often with a cancel from Cape Canaveral, Patrick AFB, or Satellite Beach FL.

On this page, "selected" indicates covers for un-manned satellite (or scientific rocket) launches only, excluding manned missions for which additional covers exist but are not included.

Whitney cachets often appear to be rubber-stamp impressions, but the straightness of the cachets on the envelopes indicates they were probably printed, although a bit weak in places, leading to the interpretation that they were done by rubber-stamp impression. Many Whitney cachets also include a date and time rubber-stamp impression specific to the launch of interest.

The table below contains only about one third of the covers produced by Whitney that are available. A list of all known un-manned satellite launch, anniversary, or event covers with cachets by Whitney can be downloaded here. Whitney also produced cachets for a large number of missile and manned missions, but they are not included either in this web page or in the downloadable Excel file. In addition, Whitney produced a few covers related to the topics of scientific research rockets and space weather. Those items are listed in the downloadable Excel file, and any of them for which we have images are also included in this web page.

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 Whitney cachets on launch covers (including anniversary-of-launch covers, and launch-related event covers).
