an explanation

I got a few emails asking, “What’s not to get about Ranganathan?” so I thought I’d proffer some info about my graphic. In 1989 an art student started a sticker campaign with this image [click for big]:

Throughout the 90s the image became somewhat of a skateboard/graffiti culture trope, was plastered everywhere, and inspired many andre the giant bootlegs. This Ranganathan one seemed natural.

something to add?
