Like Coreys' this is my ticket, card, invitation to a DANCE not a Ball Game...  Unlike Coreys' I do not have the great "in-action" image of the game and mine is merely 30 years later!  Yours is great Corey - Seems I remember you picking that up years ago?
I wish you could see this one in person - it is High Relief and I believe it is gold gilded.  It shimmers and seems to have never seen the light of day since it was made.
Some of the guys went on to play in the majors.  
Pitcher George Bradley (Supposed first no hitter) played for the Eastons at this time and was probably dancing the night away
 
Here is some info from 1874
EASTON BASE BALL CLUB.
Among the organizations in Easton is one known throughout the entire 
United States, the Easton Base, Ball Club. It was a continuation of the 
Neptune, which was organized in 1866, when the great National game was in 
its infancy, the club had a nine among the best in the State, during each 
succeeding year. In 1872, the name "Easton" was adopted, and the club 
entered for the State championship in that and the following year, but 
failed to Parry off the honors. In 1874, the club entered for the amateur 
championship of the State and the United States, in the, both of which they 
succeeded, defeating every amateur club of note in Pennsylvania, as also 
the professional Athletic and Philadelphia; the professional Atlantic, of 
Brooklyn; and the several amateur clubs of New York, who took part in the 
tournament for the amateur championship of the United States, at Watertown, 
N. Y. The prosperity of the club was mainly due to the munificence of 
George M. Reeder and W. H. Hulick. 
The "champion" team was composed of the following named gentlemen
George W. Bradley, pitcher
Thomas J, Miller, catcher
John Abadie, 1st base
John Banker, 2d base
F. W. Wadsworth, short stop
William Hauge, 3d base
William R. Parks, left field
Charles Waitt, centre field
Arthur Allison, 1st base
J. J. Smith, captain, change pitcher, and right field. 
The celebrity gained by the club in winning the championship in 1874, was 
the cause of the above players, afterwards being engaged by the Managers of 
the celebrated professional St. Louis, Washington, Boston, Chicago, and New 
Haven Clubs, to strengthen their respective organizations.
The Easton Club is still in existence, and is recognized as one of the 
leading exponents of the great National game in Pennsylvania.
