One of the key cards to the 1939-46 "Salutation" Exhibits issue is that of the young Joe DiMaggio, a celebrity by 1939 and clearly one of the most popular players of his era.  This example has been graced with a gorgeous vintage ballpoint signature, applied diagonally across the image area, the signature and its placement as elegant and graceful as one would expect from the Yankee Clipper.  The signature remains bold and vivid today, earning a grade of MINT 9 from PSA/DNA.  Corner softness, a bit of light chipping at the edges as well as some toning to the reverse, reduce the technical grade somewhat, but the eye appeal remains excellent.
