Help identifying this Warrick Dunn card

[Natedog]

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!
