1889 Boston Baseball Club Lithograph - Real or Fake?

[aquarius31]

Hi All,
Looking for opinions on this item that I just picked up. I have been collecting 19th century prints for several years now and have picked up a handful of original lithographs including a well known Prang print along with an 1888 large format Hastings print. I have provided scans below of this '1889' print. It does not display any multi-dot patterns at all and nice details under magnification although not as detailed as my larger format prints. This one is a small format measuring 12" x 9" and looks to be similar to this one offered REA several years back.

It's obviously in poor shape but still a really neat piece that will display nicely with my other prints. The foxing and thickness of the paper are consistent with 19th century prints but really would like some thoughts/opinions on whether or not this is the real deal. Thanks.
