Here's the first graf of the site's description. The actual memo is definitely NSFW. This incredible memo, purportedly issued to all Major League Baseball teams in 1898 as part of a documented campaign — spearheaded by John Brush — to rid the sport of filthy language, was discovered in 2007 amongst the belongings of the late baseball historian Al Kermish, also a respected collector of memorabilia. Essentially an on-field code of conduct, most amusing is that the memo was in fact so expletive-laden and obscene as to be "unmailable" to its intended audience via the postal service, and so was delivered by hand to each of the League's 12 clubs and their foul-mouthed players. The more things change, the more they stay the *$%^$%$#%(*&^^_(*-ing same, I guess...
