I wasn't even aware of this book until I saw it in an ebay auction. The auction copy went for $22 with shipping but there are plenty of copies BIN on ebay for around 6 bucks with free shipping.
Apparently, there was an exhibit in 2007 at the Museum of the City of New York, celebrating the three NY MLB teams of 1947-57. This is the accompanying book to that exhibit. It's filled with 350 pictures of the players, the stadiums, memorabilia and ephemera. At 6 bucks, I think it's a must have for any Giants, Yankees or Dodgers fan and anyone else who appreciates the era and/or the artifacts.
