1.75” white metal by “Davis Birm.” Obverse portrait with text “Thos. Clarkson President Of The Anti Slavery Convention In London June 12. 1840.” St. flattening of his nose. Reverse shows kneeling slave in chains with text below “Am I Not A Man And A Brother.” Surrounding the entire scene is “British & Foreign Anti-Slavery Society.” Very small surface marks on bkg. but nearly all luster remains and overall VF. Clarkson was an early and major force in the abolition movement. He is famous for a drawing of the hold of the “Crookes,” a slave ship showing how slaves were packed together for the Middle Passage. Clarkson survived an assassination attempt by slavers. A painting by Benjamin Haydon shows Clarkson addressing the convention commemorated by this medal and Haydon describes the scene at the convention as “The Aged Clarkson Came In, Gray And Bent, Leaning On Joseph Sturge (see item #221) For Support, And Approached With Feeble And Tottering Steps The Middle Of The Convention. Many Had Never Seen The Old Man Before, And All Bent Forward Eagerly To Observe Him. In A Tender, Feeble Voice (He) Appealed To The Assembly For A Few Minutes’ Meditation.” The convention responded “Amen, Amen” with many in tears and Haydon felt that the “Amen” seemed to be the “Death Warrant Of Slavery All Over The Earth."
