I'm sure some of you have seen this, but on the PSA/DNA site, they have an example of Lefty Grove's 1925 signature. But the signature clearly says "Groves" with an "s".
Does anybody know if he ever signed his last name "Groves"? I did a quick search on his name, but I haven't come up with anything that indicates he changed his name from Groves to Grove.
