John Brown Spear, US Bullet in Siberia & Ronald McDonald...

History Detective Eduardo Pagan goes sledding. It's all part of the job.

Wes Cowan gets taken on a tour of the Kennedy Farmhouse, a site selected by John Brown for his headquarters to launch his war against slavery.

Have we found the original Ronald McDonald costume? The label credits a well-known designer, and the costume is similar to the suit we see in an early Ronald McDonald commercial. But there are also some curious differences. For answers, Elyse Luray consults with a food and social historian, speaks to McDonald's first Chief Marketing Officer, and meets the widow of an early Ronald McDonald clown.

Watch some McDonald's commercials from the 1960s (no audio).

Wes Cowan looks into whether this antique spear weapon was part of abolitionist John Brown's notorious Harpers Ferry raid. Our contributor bought the spear, or pike, from an antique shop in Chagrin Falls, Ohio where John Brown is known to have lived. Follow Wes on the trail to the blacksmith who forged the weapon over 150 years ago and the ground at Harpers Ferry where the battle took place.

A World War I vintage cartridge discovered by a viewer in Colorado contains a curious etching: Leo V. Thompson, CO E 31st Inf., A.E.F. Siberia. Nearly 40 years after he paid one dollar for the bullet, our contributor still wonders about Leo V. Thompson and what United States troops were doing in Siberia after the First World War. Follow Eduardo Pagan as he tries to track down the answers.
