Behold, the NYPL's AG Spaulding Baseball Collection. Over five hundred lithographs and daguerreotypes, including a great many of the Phillies (nee Quakers) and their erstwhile crosstown neighbors, the Athletic.
Take a gander at Quakers Charlie Ferguson, wearing an onion on his belt, as was the style at the time; or Arthur Irwin, who seems to be signalling "safe" even as he tags the runner (named Tom McCarthy) out.
All kinds of great stuff there. H/T to Mrs. Phrozen for the links.
