The pieces in this show are not for sale, in the usual sense (of the artist and the gallery making money on the sale). Getting a Congolese child out of the cobalt (used in mobile phones) mines and sending him to school costs $25 per month ($300 per year) so the "pricing" is as follows:

A $300 piece provides one year of school for one child; a $600 piece provides for one year of school for two children; a $900 piece provides for one year of school for three children; a $1200 piece provides for one year of school for four children.  The money will be donated through Global Giving in Jose Ramon's name.
