Size: 10.8 x 10.8 cm.
Manufacturer: Owens Corning Fiberglas Corp.
Description: This patch corresponds to the second design variant without the black outlines of the lettering and Earth, thus avoiding some errors of misalignment during the production of the previous version.
This variant also presents a simplification of the details in the landmasses on the Earth and in the dark crater details on the lunar surface.
It's not clear when the design was changed but this variant is the one included in the complete Apollo project presentation piece created by Owens Corning in the mid 1970s and is also the version incorporated in the Owens Corning Apollo 11 lucites.
This particular patch in my collection seems to have been stitched by a previous owner for presentation purposes.
