About the item: From the 1993 Star Trek Masterpieces trading card set, this card features a scene from the classic Star Trek episode "The Trouble with Tribbles." It is autographed by both Nichelle Nichols and Walter Koening. Please note- the signatures are real. They are the actual, hand-signed signatures of Nichols and Koening. They are not pre-printed images on the card. The card is in near mint / mint condition and will be shipped with the utmost care. ~Certificate of Authenticity/Provenance: Excepting pack-pulled autograph trading cards, CGC Signature Series, signed Sideshow prints, and like collectibles, all autographed items Vault Collectibles sells were personally witnessed, by myself, being signed by the writer, artist, or celebrity in question. No third party is involved. Further, art sketches - and most published original art I sell - were obtained directly from the artist themselves.
