This is one of the popular early to mid 19th century birth/baptismal certificates, known as "Geburts und Taufschein", 16 1/2" by 13 3/4" in thin strip framing, printed by G.S. Peters of Harrisburg, Pennsylvania, the name of the child and the parents written by hand along with other details such as place and date of birth. In this case the parents are William and Margarethe Bitzer (nee Harvey), and the child, named Michael Bitzer, was born in Greene Township, Ross County, Ohio (near Chillicothe in the south-central part of the state). The baptism was by Rev. Paster and the witnesses were Jacob Fredric and wife Elizabeth. Date of birth, curiously, is given as October 2, 1805; I think this certificate would have been printed several decades later, so I feel it possible this might be a replacement of some kind. Most of these certificates have later dates, to the 1830's or 1840's or even later. The condition has been somewhat compromised by long contact with acid-leaching cardboard backing, and there are two major horizontal folds, as well as various other flaws such as tiny paper losses in the folds, discolorations, and handling creases----all of which, to me, add to the history of the piece.
