I have come across a lot of Gonterman's prints, but nothing original. He was good, popular for pencil portraits of famous Americans. He was not great though and has not appreciated in value at all. Many of his works had a "signature" of his subject also that was also well done. I would have no opinion on the Gehrig inscription being real or not, other than stating again much of his work has very close "signatures" of his subjects. You can probably find his stuff on ebay from time to time.

Here is one of his of Thomas Jefferson as an example. (pulled from eBay)
