A new exhibit connects early mining and the delivery of mail.

As Tucson welcomes the annual gem and mineral showcase, the Postal History Foundation reviews the connection between the early days of mining in the American West and the delivery of the mail in the exhibit, “Prospectors and Postmen: Mail Delivery in the Boom Days of Mining.”

The exhibit presents photographs, contemporaneous mail, and other documents to tell the story of early mail and freight transportation. It also includes information on Colorado River steamboats, pack animals, wagons, coaches, buckboards and “pony express” style horseback mail delivery.

The exhibit is in the Peggy J. Slusser Memorial Library at the Postal History Foundation, 920 N. First Ave., between First and Second Street. Admission and parking are free. Slusser Library hours are Monday-Friday, 9 a.m.–3 p.m.
