Trotsky Ice Axe

1928, Austria

Ramón Mercader hid this shortened ice climbing axe under his suit jacket, suspended by string. Look closely: a rust mark from his bloody fingerprint is still visible on the blade.

The Mexican Police Department kept the axe as evidence, later putting it on exhibit. When its museum director retired in the 1960s, he received the axe as a retirement gift. For 40 years, his daughter slept with it under her bed.
