Item 24 is George Catlin's very rare pamphlet, An Account of An Annual Religious Ceremony Practised by the Mandan Tribe of North American Indians. Catlin was reluctant to discuss this violent religious ceremony, but agreed to submit an account in writing to London's Philobiblion Society in 1865. The Society promptly published this account in 50 copies. Catlin was upset. He disavowed authorship and demanded all copies be surrendered. Quite obviously, his demand was not met. Still, this item is extremely rare, this being the Siebert copy and apparently the only one on the market in the past 25 years. $17,500.
