It took me a while -- Google was
not my friend in this case -- but I did find some close ones
here,
here, and
here, and
this one might fit Dave better during pre-Kickoff, but I couldn't find a clear photo of his shirt --
this was the closest. (You'd think in 35 pages of Google images it would come up?) Still blurry, but it's still, uh, greek to me? (I do have a good image -- but on a different computer.)
