A vintage Secret Service pin-type badge used in Texas on November 21–22, 1963, measuring .75 x 1.5, featuring repetitive text on the front in extremely small type, “Secret Service Treasury Department United States,” with bold text imposed over this pattern, “A 42 USSS.” Text on the reverse reads, “Return to U.S. Secret Service, The White House.” The badge is attached to a metal clip engraved with the name of the maker, “Plasticmaster, Los Angeles.” Includes a notarized letter from Martin E. Underwood to the original purchaser, Robert L. White. In part: "I turn over ownership of my secret service official clip on pin which I used in…Texas…I advanced the Houston Texas trip for President Kennedy…The clip on pin you now have was mine which I was wearing." In fine condition. Originates from the Robert L. White collection and is accompanied by a certificate of authenticity from Erik L. Dorr, which also states that it was deaccessioned from the Gettysburg Museum of History in 2010. A fantastic, government-issued item actually used in an official capacity during the ill-fated Texas visit. RR Auction COA.
