American financier (1836–1892) whose speculative attempt to corner the gold market led to a financial panic on September 24, 1869 that became known as “Black Friday.” Handsomely engraved color pass for the Erie Railroad issued to Russell Potter of the Cincinnati & Indianapolis Junction Railroad Company, 3.25 x 2, 1869, clearly signed in ink “Jay Gould.” A touch of light soiling, otherwise fine condition. An attractive and uncommon format! R&R COA.
