Flip it Over!
I've been quickly going through a few things in my grandparents' collection of clippings trying to find something for a Casefile Clues column. I ran across a clipping Grandma made from the church bulletin the Sunday I was baptized.
While she didn't write the date on the clipping, I was lucky. When I flipped the clipping over, the date was right there on the back: 28 July 1968.
The name of the church wasn't there, but that I already knew--Trinity Lutheran in Carthage, Illinois.
I'll have to work on a citation for this in the spirit of Evidence Explained. Everything used in Casefile Clues is always cited, but this probably won't appear there as I usually don't write about myself.
