The U.S. Postal Service plans to release a pictorial postmark in recognition of the Indiana Bicentennial Torch Relay on Thursday.

With the purchase of a postal card or forever stamp, the postmark may be affixed to a piece of mail.

The postmark is the fourth in a series produced for the bicentennial. Earlier postmarks, measuring 2-by-3-inches, were issued for the opening of a time capsule at the Jackson County Courthouse in Brownstown and the founding of Jackson County and of Brownstown in 1816.

The torch relay postmark will be available at the Brownstown Post Office for 30 days.
