This signature card from the Key Biscayne bank in Florida is far better than any cancelled check when it comes to signatures. This particular card is signed by both President Richard Nixon and First lady Patricia. The card gives power of attorney to Loie Grace Gaunt should it become necessary. The card measures approx. 4 x 6” and the condition is EX with no wrinkling or paper loss. The signatures themselves are written in blue and black ink and both are high quality, earning a rating of 9. Presidential Signatures are always incredibly valuable and though Richard Nixon may not conjure the most venerable of emotions, he will forever live in infamy when it comes to U.S. politics.
