“Notorious RBG” started out as a Tumblr fanblog created by law student Shana Knizhnik. After a wave of publicity (and the blessing of the justice herself), Knizhnik has co-written a biography of Justice Ruth Bader Ginsburg with Irin Carmon. Notorious RBG: The Life and Times of Ruth Bader Ginsburg is an ideal book for any Ginsburg fans. In addition to the now-classic “Notorious RBG” T-shirts and mugs, you can also pick up “The Ruth Will Set You Free” and “Queen Supreme” merchandise.
