The mystery is solved.
A missing state historical marker showing where prominent 19th century Pittsburgh abolitionist Martin Delany published his anti- slavery newspaper, The Mystery, has been found, just weeks before Delany is to be honored in Washington, D.C.
The marker stood at 5 PPG Place, between Third Avenue and Market Street, Downtown, but PPG work crews removed the damaged pole on which it was mounted during the winter. They took the marker to a utility room for storage, where it was discovered, Anita Falce, PPG's marketing manager, said Monday.
A spokeswoman for the Pennsylvania Historical and Museum Commission, which placed the marker in 1991, said a new pole will be sent so that PPG can remount the sign.

A physician, he became active in the Underground Railroad and worked closely with abolitionist Frederick Douglass, engaging in epic debates about slavery and free society.
He started his newspaper from a storefront near Market Square in 1843.
"Delany came to Pittsburgh because it was a comparatively progressive city" for the time, said Laurence Glasco, a University of Pittsburgh history professor. "Blacks in Allegheny County ran their own schools out of churches, and he married a Pittsburgh girl.
"He became a leading citizen. He had lots of respect from the white population," Glasco said.
The museum wants to honor Delany for his accomplishments, which stirred debate in the United States on the …
