Two months after Marion Shurtleff walked into a San Clemente, California, used bookstore and bought the book, she realised the yellowed pages stuck in it were penned by her own hand 65 yrs ago when she was known as Mary Lou Hesser.
"And then I opened it up, and instantly I saw my name. I recognised my handwriting. I hollered. I started shaking. I cried. I had goose bumps," she told KCAL-TV.
Shurtleff was 10-years-old when she wrote her essay to earn a "foot traveller badge" for her Girl Scout troop in Covington, Kentucky, the 'New York Daily News' reported.
Her troop leader, Bonnie Jean Edwards, signed the top, the last link Shurtleff can think of to her essay.
The edition of "The People's Study Bible" was printed in 1986, the Orange County Register reported.
Shurtleff has tried to get in contact with the people who sold the book to the used bookstore. She's holding out hope a relative of Edwards will get in touch and explain why the essay was in the book - and why they held on to the essay for all these years.
