This unlined 3x5 file card has been signed by Malcolm X in red ballpoint or biro pen. It is inscribed "Hold fast! Bro Malcolm X". The signature was obtained in New York by Stanley Kolowski, who along with his wife Stephanie, started collecting in-person autographs in the 1950's. The card had been glued into their scrapbook for about forty years. Other than some adhesive residue on the reverse, the card is in excellent shape.
