As she says:
This is an Art Piece I created as a reaction to Ray Comfort's blatant and willful ignorance. If you don't "get" this piece, that's a sign that you still have your faith in humanity. I realize this piece is somewhat anti-feminist, but so is Ray. Profits from the sale of this item will go to a program supporting young female paleontologists. Tampons ARE included.
And it can be your for the low low price of $10 (plus S&H). Act now! Operators are standing by!!!
