Busy Beaver Button Museum founders Christen Carter and brother Joel visited Washington D.C. last weekend for research at the Smithsonian, and also prepared custom buttons to distribute at the Rally to Restore Fear/Sanity taking place the same weekend.

Only 100 buttons with the “Busy Beaver Thumbs Up to Sanity” were distributed at the event, and another 50 were sold to collectors online.

There’s just a pinch left of the dated buttons available on the Busy Beaver Etsy Shop here.
