Enjoy this Family Pass to the Baltimore Museum of Industry.  

From the BMI Website:

"Unlike many of America’s museums, the Baltimore Museum of Industry’s collections do not document the lifestyles of the elite. You will not find fine art or furnishings. Rather, the 100,000 objects the BMI holds document the often-overlooked people in history-the workers, small business people, and citizens who built America.

Baltimore has long been recognized as one of the nation’s premier industrial centers, home of the nation’s first passenger railroad; the world’s largest copper refinery; the oldest gas company in America; the first traffic light, and a multitude of other technological innovations. Baltimoreans have a reputation for taking great pride in their city’s identity as a “working man’s town”—a pride that has been enhanced and celebrated by the city’s renaissance and emergence as a major tourist center.

The BMI’s collections are evocative reminders of Baltimore’s great history. They explain more effectively than any textbook, how the city developed from a small trading post to a thriving, industrial center of manufacturing and commerce in a few decades. The collection also explains how a visitor’s ancestor, no matter his or her station in life, race, ethnic background, or occupation might have contributed to this development. This heritage, central to Baltimore’s image of itself, is only being preserved at the BMI.

Baltimore has entrusted the BMI with its artifacts, images, and records- creating one of the nation’s best and broadest collections of industrial items relating to a particular place and its past experiences.

Some items that are highlights of the collection include an historic 1850s shipyard bell; an early wooden gas pipe laid by the nation’s first gas company; a rare 1820s “Acorn” printing press; a 1922 Linotype machine-a typesetting machine that revolutionized the printing industry and was invented in Baltimore; antique sewing machines, and the entire collection from the Mount Vernon Museum of Incandescent Lighting."
