This scan of what I believe to be a page from a Japanese magazine has been making the rounds on Twitter since the Phillies won the pennant on Sunday. It shows heavy metal icons Iron Maiden wearing Phillies caps and what appear to be bootleg team uniforms. According to Google Translate, the large bold text in the caption reads "first attempt at baseball!!" and the smaller white text below translates to "a country without baseball, the heroes of the British rock empire become a rock powerhouse". Unfortunately, there was no source provided with the image, so I'm not sure what year it's from or what magazine it was published in.
