I'm auctioning off one of my oldest and most reliable brushes for charity through the Brush Project in Chicago. You can have a look at all of the brushes on ebay as of today. View all of the brushes here. Good Luck.

DvA Gallery will be auctioning off original artists brushes that have been used in creating their artwork to help raise money for the efforts of Americans for the Arts, the nation's leading nonprofit organization for advancing the arts in America. The brushes will be signed by the artists and framed in shadow boxes then put on display at DvA Gallery on Saturday, July 21st. The auction will start Friday the 20th and will go on for 7 days. Each brush comes with a Certificate of Authenticity!
Americans for the Arts advocates for policy developments that increase the visibility and stability of arts education in the nation. For many of America's youth, public schools serve as the major provider of formalized arts instruction. Therefore, it is critical that the arts maintain their status as a core academic subject within a school district's educational mission and that they are adequately funded. Because the visual arts are vital to the development of our children and our communities, Americans for the Arts strives to provide and secure more resources and support for arts education.
