A Nagarjuna (we assume) mask S bought in Nepal while he was shooting.
It's old and the person S bought it from would only say, "from hills! Old from hills!", probably because S didn't speak Nepali and the proprietor didn't speak Hindi or Punjabi.
And...I love Samuel L. Jackson, so I thought it was only appropriate for my snake-themed mask to advertise his new snake-themed movie (I love the internets).
