Legendary Auctions appears to be the place to pick up some vintage early 20th Century Baseball photographs. They have original pics from Baseball photographic legends Paul Thompson and Charles Conlon, and examples from well regarded news institutions like UPI and the Detroit News. Fortunately, their impressive collection includes a ton of Dodgers. Go here to check out the entire auction offering. It's filled with the "Who's Who" of deadball era greats.
Below are a couple of nice photos of Baseball and Dodger legend Branch Rickey during his playing days with the Cardinals.
Here is a original Paul Thompson photograph of Hall of Famer and former Dodger Zach Wheat- from the days when the "Boys in Blue" wore pinstripes.
Charles Conlon produced the Nap Rucker photo below. It has to be from 1916 since it was the only year Rucker was on the team when they wore checkered uniforms.
From either 1916 or 1917, below is a Charles Conlon photograph of Chief Meyers. (Most likely from 1916, because of the little "B" on the chest.)
Once again, I can never get enough of Babe Ruth in a Dodger uniform. I think I like this photo the best since it shows Ruth in the 1st base coaches box during a game. This is a UPI Press Photo.
