This was an album that could be mailed away for from the Allen & Ginter company. 20 coupons would get this string-bound album in which to house one's cards from the World's Champions
set of 1888 by A&G. The front cover and inside pages are ornately decorated and colored; the back cover is blank. There are 12 double-sided pages inside with spaces marked to paste
the 50 cards of that year's baseball set.
This item measured 6 by 8 inches.
Not too many examples have survived to the present day; this is considered a very desirable baseball collectible in its own right.
