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.

The goal is to raise $10,000.00 to help pay for the meetings, banquets, banners, plaques and other expenses associated with our 2011 Centennial Celebration. You may purchase as many T-shirts as you wish. Once we have sold 200 we will have reached our goal of $10,000.00 and will stop selling them.
You can order these collector edition T-shirts from our online store.
You can also simply make a donation to the centennial fundraiser online at http://www.aavso.org/make-gift by designating your donation to the Centennial Celebration Fund.
