A bicentennial celebration planned for 1 to 5 p.m. Sunday at the Jackson County History Center will feature a presentation about the Brownstown Post Office.

Carol Newberry, postmaster at the Brownstown Post Office, will talk about the history of that office, which was established in 1816.

Newberry will cancel mail using a special pictorial postmark made especially for the Indiana state bicentennial, which is Sunday.

Jackson County celebrated its bicentennial Jan. 1, and Brownstown celebrated its 200th birthday April 8. Pictorial postmarks were issued by the postal service for those two celebrations, and others were issued for a time capsule opening April 2, 2014, at the Jackson County Courthouse and the Indiana Bicentennial Torch Relay on Sept. 15. A limited number of postmarks from those events are available.

Children who have 1966 wooden nickels, which were passed out in recent years, may bring them to Sunday’s bicentennial celebration. They will be recognized and receive a gift.

The event also will offer a last chance to purchase chances to win the commemorative bowie knife handcrafted by Todd Hunt of T.M. Hunt Custom Knives of Seymour. The drawing for that knife will be Sunday during the bicentennial celebration.
