Green tinted Exhibit postcard signed by Cobb in black fountain pen across the front. Signature rates 7 out of 10 and is noted as one a very small number of known Cobb signed examples on this medium. Card front presents with excellent eye appeal with some scrapbook adhesion removal abrasions on back accounting for technical card grade. Encapsulated by PSA/DNA: Autograph (7 NM) and Card (1 Poor)
