To help support our 2011 Centennial Celebration the AAVSO is offering special commemorative T-shirts in exchange for your $50.00 donation to the AAVSO. This was a limited edition run of 200 shirts only (update: about 130 left as of May, 2011). Once they are gone they are gone. We will never produce these collector items again.
