A beautiful item that was displayed at the 1893 World’s Fair will be coming up for auction on December 6, 2017.

Geneva Armstrong’s model cattle car (Jackson’s Auction)

Exhibits in the Woman’s Building showcased the achievements of many women inventors. Among them was Geneva Armstrong, who displayed a model of the railroad stock car she designed and patented, which had an adjustable trough for feeding and watering cattle.

Armstrong’s original model is offered as Lot 1155 by Jackson’s Auction in Cedar Falls, IA, in their “World Treasures: Featuring Important Native American, Asian, European & American Works.”

The 16.75-inch-high and 8-inch-wide model train car is made of walnut and machined brass and comes with its original wooden travel case, having hinged end panel and an exhibitors printed label stating “To the Director General of the World’s Columbian Exposition Chicago, 1893. Woman’s Building.” This one-of-a-kind Columbian Exposition relic has an auction estimate of $500-1,000.
