This Apollo-Soyuz Test Project patch is possibly part of a set of modern reproduction Apollo patches produced by Cape Kennedy Medals. It appears to be identical to the A-B Emblem version, however minute, subtle differences can be found. The gold stars appear to be sewn on top of the red field rather than being holes in the red field as in the A-B Emblem version.
Found in auctions adjacent to other Cape Kennedy Medal Apollo patches.
