Eagle One Aerospace produced an exclusive set of Project Mercury crew patches in the early 90's. 5 sets were produced and mounted on a poster, another 25-50 were produced as an unmounted set. Each patch has the hallmark initials of their respective crewman. They faithfully render the capsule artwork and are often considered to be the proper mercury crew patch as opposed to the common, later souvenir patches from A-B Emblem and others. 

This is a vintage, but high quality patch. The embroidery is better than that of regular souvenir versions and more closely matches the crew souvenir versions. Cloth back.

This Apollo 7 patch is part of a set of modern reproduction Apollo patches produced by Cape Kennedy Medals. 

This is the Swissartex version of the Apollo 7 3" souvenir patch. 

Commong A-B Emblems 4" souvenir version.

The gray lettering is distinct in this version.

Collected as a set with other 3" Mercury and Gemini patches. This set of patches, while at first glance appear to be regular A-B Emblem 3" souvenir versions, actually have some distinct oddities that set them apart. They all have cheesecloth backs.

Cape Kennedy Medals 3 1/4" Apollo 7. Packaged with collection that included Cape Kennedy Medals 3 1/4" Apollo 9 and Apollo 13. 

I am making a leap that this version is CKM due to the unique 3 1/4" size as well as the associate with at known CKM issue Apollo 9 in the same set.

This patch is a member of a set of Apollo patches that, while closely resemble A-B Emblem's 3" set, have several identifiable differences that set them apart.

New embroidery style, strangely depicting "VII" and continents in gold thread. 
 

Similar to A-B emblems version, but newer embroidery style

Less common than the regular Lion Brothers issue, this features a purple twill background.

This patch is the patch issued by Schirra's office. It appears to be a combination of the souvenir version (with 'GTA-6') and the worn version, with the detailed embroidery).

This patch is identical to the original patches worn by the astronauts when the flew into space. The souviner version is slightly different and says 'GTA-6' instead of 'Gemini 6'.

This is the patch that the astronauts wore in training, though it has become the common, souvenir version. The design worn in space is slightly different.
