The STS-7 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.
The AB Emblem patch was the version used by the crew.
The Lion Brothers STS-7 mission patch has a plastic coating on the reverse.
The vintage version of the Swissartex STS-7 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 can be readily identified by the radial fill pattern in the red outer area.
This Cape Kennedy Medals patch has blue shading on the Shuttle like the Swissartex version but doesn't have the same radial fill pattern in the red outer area.
