Government postcard, postmarked January 14, 1937, beautifully inscribed "Sincerely Babe Ruth" on the front in black fountain pen. PSA has encapsulated the card and graded the signature MINT 9. This is an exceptional Ruth signature example, the demand for which has always exceeded the supply, making it both ideal for display and a sound hobby investment. The postcard (5.5x3.25") is slightly toned and displays light adhesive-residue lines on the mailing side from having once resided in a period photo album. Excellent condition overall.
