The Lion Brother's Apollo 14 patch, like many others, closely resembles the crew version and is a better rendition than the A-B Emblem issue. 

It is a cloth-backed patch. This is the first Lion Brother patch with a hidden hallmark and it is very difficult to make out, it is sewn with a single width of thread. 

This Lion Brother's version of their Apollo 12 lacks the hallmark "12" in the Intrepid's path. It also features horizonal gold border instead of the radial of the hallmarked version.

Similar to the A-B version but can be identified by the two colors of shading on the right side of the earth.
