om Bradshaw and Ron Stawback are avid football fans; Bradshaw is a rabid Pittsburgh Ironmen supporter, and Stawback's favorite team is the Dallas Cattle Ranchers. The two teams are bitter rivals, and are scheduled to play during Week 4 of the 2008 United Football League (UFL) schedule.

Before the season starts, Bradshaw and Stawback wager a bet that their respective teams will win in the Ironmen-Cattle Ranchers clash. Bradshaw presents $500 in cash to secure the bet, and Stawback produces a written "I.O.U.," stating the following: "In the event that the Pittsburgh Ironmen defeat the Dallas Cattle Ranchers in Week 4 of the 2008 UFL season, I promise to pay the sum of five hundred and no/100 dollars ($500) to the order of Tom Bradshaw. Signed, Ron Stawback."

 

In Week 3 of the UFL season, Bradshau indorses and transfers the Stawback I.O.U to Kenneth Steibler, in payment of a lost $500 bet to Steibler (Stieber's favorite team, the Oakland Swashbucklers, defeated Bradshaw's Ironmen in Week 3.) In Week 4, the Ironmen defeat the Cattle Ranchers.

Can Stieber recover the $500 face amount of the I.O.U. from Stawback?Explain
