Bold signature in black fountain pen on a small white card, 3.75 x 2.5.  A pencil annotation along the bottom edge; otherwise very fine condition.  The card is currently housed/encapsulated in a plastic holder, like a precious fossil, with certification by third-party authenticator PSA/DNA and it has been scanned through the plastic, rendering the accompanying scan slightly fuzzy.  The card can be removed from the plastic holder if so desired.
