For me, a trip to Barnes & Noble during the Christmas season included perusing the signed copies of new books written by famous people.
I looked at more than a dozen of these books, curious to see if the penmanship was as well-crafted as the printed words in the works of nonfiction and fiction.
The signatures: Some good, others bad.
I looked at copies signed by actresses, an actor, musicians, retired athletes, celebrity chefs, children's book creators, a reality TV celebrity, a feminist and an author of thrillers.
And I used my iPhone to take pictures of the signatures that appear on one of the opening pages of their books.
A good signature is one the famous writer apparently took time and care to write. It is distinctive. It has flair.
A bad signature is scribble scrap. It seems the famous writer spent just micro-seconds signing the book. I would give them a grade of F for effort.
In the series, the only hint I gave was the title of the book.
The signature at the top of this post is from the book "50 Years, 50 Moments: The Most Unforgettable Plays in Super Bowl History," co-authored by San Francisco 49ers great and Mississippi native Jerry Rice.
I am a fan of the man and his autograph.
This is the end of the "Who wrote this?" series.
