Help identifying this Warrick Dunn card
 

Hi, my neighbor has several boxes of cards he asked me to go through to see if there was anything of value. One interesting card I found was this Warrick Dunn, which has a "1/1" over the word "spectrum" on the back. I collect more vintage and a little modern baseball, so I was hoping someone here could help me identify it. I've never posted a pic on here before, so I hope it works. Thanks!
