The following link A page in http://www.spaceflownartifacts.com/flown_license_plates.htmlSpace Flown Artifacts describes miniature lunar rover license plates that Dave Scott carried to the moon and back:
"These miniature license plates were manufactured by Boeing (makers of the Lunar Roving Vehicle itself) especially for Apollo 15 commander Dave Scott as a memento of the first lunar rover. The miniature plates were made of lightweight aluminum and measure just 1¼" x ½" (32mmx20mm) in size. They are marked with the registration number "LRV 001", with "MOON" as the home state, the year 1971, and the NASA and Boeing logos. The plates were prepackaged in a pack smaller than a pack of gum, which was stowed in the left knee pocket of Scott's space suit before the launch and remained there until after his return to Earth."

Question: Did Dave Scott receive Deke Slayton's approval to carry these miniature license plates, or were they smuggled along with the famous Sieger covers (https://en.wikipedia.org/wiki/Apollo_15_postal_covers_incidentSieger covers)?
