STS-41C
The STS-41C crew wore the standard AB Emblem embroidered mission emblems on their flight suits and on their in-flight clothing, thus there is no rare 'crew patch' for this mission.
Embroidered Mission Patches
A-B Emblem patch
The AB Emblem patch was the version used by the crew. Note that some later versions of the AB Emblem patch added a merrowed border to the patch although the design remained otherwise identical.
Lion Brothers patch
The Lion Brothers STS-41C mission patch only exists with a plastic backing. It features a paler yellow thread than the other versions, contrasting with a much darker blue fill for the background space.
Swissartex patch
The vintage version of the Swissartex STS-41C mission patch exists both with a waxy plastic backing and with a vacuum sealed
clear plastic coating on the reverse. The fronts of the two versions are virtually identical.
The patch has a distinctive ridged fill pattern to the dark blue background space.
Cape Kennedy Medals patch
The Cape Kennedy Medals patch uses a distinctive orange color for the arms of the sun/star.
