Legendary Auctions is currently running their August auction and it includes a couple of Dodger related items of note.
Below is a great vintage, circa 1950's, photograph of Duke Snider.
Here is a great advertising piece for Coca Cola featuring Dodger catcher and spokesman Roy Campanella. This piece dates to 1952 and would typically be seen on the counter top of your local soda shop. This style, with Campy, was distributed only in the New York area and is fairly scarce. Be forewarned, I've seen fakes before (especially on eBay) so be careful if you ever consider buying one.
