I picked up this awesome baseball from Ebay recently. I have been looking for antique baseballs over the last couple months and have finally gotten one. I had no idea how expensive they were (I've seen some figure eight style baseballs selling for $200.00 on ebay).
No, there is no way it is an autograph. It is clearly scratched into the ball.
I imagine some kid owned it back in the late 20s - early 30s and imagined themselves calling a home run shot. What would be really awesome, but never able to be proven would be if this ball was a Ruth home run ball. Or maybe a foul ball? The speculation is endless.
