This is up for auction in Japan right now, an autographed ball with Ruth, Gehrig, Foxx, etc from the 1934 All star tour of Japan:

No authentication and the seller provides zero description of the item (the Japanese text in the listing is just boilerplate language about the seller's policies against returns, etc.)
Cool item if its real but I get a bad vibe from the seller and was wondering if any autograph experts had opinions on the autographs themselves.
