Underwear on display in Salem

SALEM — The Salem Historical Society & Museum may have the most interesting exhibit during Smithsonian Magazine’s Museum Day: underwear.

The day is designed to highlight museums across the nation. Some 651 museums across the nation took part last year, and more than 900 museums are participating this year.

People can go the magazine’s Web site and print out free admission tickets to the museum of their choice.

It’s the fourth year of Museum Day and the first year the local historical society is taking part, said director David Stratton.

The society will present its ongoing exhibit called “Victorian Secrets” that reveals the basics of dressing. It is mostly focused on the Victorian era that began in the 1830s and ended in the early 1900s.
