Naval Covers

This section lists active links to the pages displaying covers associated with the ship. There should be a separate set of pages for each incarnation of the ship (ie, for each entry in the "Ship Name and Designation History" section). Covers should be presented in chronological order (or as best as can be determined).

Since a ship may have many covers, they may be split among many pages so it doesn't take forever for the pages to load. Each page link should be accompanied by a date range for covers on that page.

This section lists examples of the postmarks used by the ship. There should be a separate set of postmarks for each incarnation of the ship (ie, for each entry in the "Ship Name and Designation History" section). Within each set, the postmarks should be listed in order of their classification type. If more than one postmark has the same classification, then they should be further sorted by date of earliest known usage.

A postmark should not be included unless accompanied by a close-up image and/or an image of a cover showing that postmark. Date ranges MUST be based ONLY ON COVERS IN THE MUSEUM and are expected to change as more covers are added.
>>> If you have a better example for any of the postmarks, please feel free to replace the existing example.

Other Information

NAMESAKE - Seaman Apprentice William R. Flores, USCG (6 November 1961 - 28 January 1980)
Flores was born and raised in Carlsbad, New Mexico. On January 28, 1980, 18-year-old Flores stayed aboard the USCGC Blackthorn WLB-391 as it was sinking following a collision with a tanker, SS Capricorn, and helped save twenty-three (23) of his crewmates, at the cost of his own life. Flores and a colleague threw their life jackets to seamen struggling in the water without life jackets. He strapped the life jacket locker open, so remaining life jackets would be released as the vessel sank. He then tried to aid wounded seamen who were still aboard. For his bravery, SA Flores was posthumously awarded the COAST GUARD MEDAL. The Coast Guard Medal is the highest non-combat bravery award of the United States Coast Guard.
In May 2021, Flores was awarded the Texas Legislative Medal of Honor for his actions on the USCGC Blackthorn.
