Signed by Lou Gehrig on the sweet spot and highlighted by a vintage red semi-circle stamped around it, this is one of the more interesting Lou Gehrig single-signed balls we've handled. Although faded, Gehrig's signature is found perfectly on the sweet spot and grades about 4/10. Ball itself is an Official American League version, the labeling has faded slightly but is still present. It has also been shellacked and features a nice vintage cream color. The original owner of this unique ball later wrote the names of all of Gehrig's Yankees teammates and other superstars of the time in block letters; had he only known to leave it alone. Comes with full JSA letter.
