Flight crew emblems for all Apollo and Skylab manned missions. These cloth emblems are noted for their detailed artistry and exceptional quality of the official NASA crew designs. The Apollo 12 through 17 emblems are hallmarked in the form of their respective mission number "hidden" in the embroidery. Hallmarks are located in Apollo 12's Clipper ship dust trail, in a horse mane just below the sun for Apollo 13, upside-down in the white lunar surface for Apollo 14, just above the "D" in Worden on the Apollo 15 emblem, under the gold vector on the right for Apollo 16, and in the shoulder of god Apollo for Apollo 17.
The Skylab series has the initials of the crew’s last names with “CKW” for Conrad, Kerwin, Weitz found just to the right of the Skylab space station. “BGL” for Bean, Garriott, Lousma is found in the lower part of the sun just above the letter ‘S” in Skylab II. And for Skylab 3, CGP for Carr, Gibson, Pouge makes up the leaves in the tree found at the upper section of the large “3.”
