1488

 Anyone know what that number symbolizes?

Here it is:

1488 is a combination of two popular white supremacist numeric symbols. The first symbol is 14, which is shorthand for the "14 Words" slogan: "We must secure the existence of our people and a future for white children." The second is 88, which stands for "Heil Hitler" (H being the 8th letter of the alphabet). Together, the numbers form a general endorsement of white supremacy and its beliefs. As such, they are ubiquitous within the white supremacist movement - as graffiti, in graphics and tattoos, even in screen names and e-mail addresses, such as aryanprincess1488@hate.net.  Some white supremacists will even price racist merchandise, such as t-shirts or compact discs, for $14.88.

So, the following image might just be a coincidence then?
