3-Muscateers

‘3-Muscateers’ covers were made by Stan Henderson of 813 Spruce Ct, Rodeo, California / 2565 Downer St, Pinole, California. According to the Collect Space website, Stan Henderson was very active during the 1970s but not much is known about him after that. My collection of these interesting covers is shown below. They often seem to have been cancelled on multiple dates, which makes it difficult to list things chronologically. I’ll try use the earliest date on each cover where possible otherwise the most significant date / event.

Some 3-Muscateers ‘extras’ are shown here.

* = not branded 3-Muscateers, but cover(s) serviced by Stan Henderson and clearly belong here.
