There is a really interesting photo album of for auction in Japan right now:
http://page11.auctions.yahoo.co.jp/j...ion/n183544238
It has 128 photos taken in the 1930s, mostly of random stuff (family, soldiers, bridges, scenery, etc). But several of them were taken during the 1934 American all stars tour, and there is a beauty of a picture of the Babe sitting in the dugout.
Bidding is up to 96,000 Yen (about 1,000 US$) at the moment, its quite the interesting find.
