Signature Memorabilia

"The items in this unit are good, right?" Li Du asked. "Are the signatures authentic?"

Sophie looked at the basketballs, footballs, baseballs, and so forth. "Are there signatures on them?" asked Sophie. "Wow, there really is—"

"Of course there are signatures," Hans interrupted, "and they're real! Dwyane Wade, Kobe Bryant, LeBron James, Allen Iverson, Shaquille O'Neal!

"And these footballs! Santonio Holmes Jr., Eli Manning, Peyton Manning, Hines Ward, Deion Branch, Tom Brady! D*mn, that's awesome!"

As he read the names, he became so excited that his eyes started glowing.

"All of them are stars, right?" Li Du asked.

Hans did not respond. He continued checking out the items. He became more and more excited and finally cried out, "D*mn, bud, we're going to be rich. This time, we're really going to get rich!"

Li Du inquired, "Are all these signature balls really valuable?"
