Does it cover 1880's-1890's era extensively with all player bios with detail? I find myself very fascinated with that era of hockey & its many great forgotten players.
If you're interested in that era you might like "Win, Tie or Wrangle" by Paul Kitchen. It is a history of hockey in Ottawa (not hockey in general) but it is a pretty hardcore history book which goes into a lot of detail on the birth and evolution of the game and leagues that turned into the NHL. It is not a light read but there's a lot of great detail you can't get in many other places. It gives you a great feel for the early days of the game.
I'd love to get the Trail of the Stanley Cup (I've never even seen a copy but just from the description). I guess there's no inexpensive alternative is there? The NHL should consider re-releasing it - the original printings should still hold their value even if it came out again I would imagine (most of them seem to be personalized to some hockey great and would still have collectors value).
