The baseball card of Panick is from the 1977 Salt Lake City Gulls set. Panick was a non-roster invitee with the Angels in 1975.

I have a hunch on the identity of KF 197 & 198. However, because I'm not certain, I'm continuing to look through all the pitchers who were on the spring rosters or were NRI's of the Angels during the 1973-1985 period. The patch on Panick's uniform leads me to believe that's the period in question. The photos of the lefty in KF 197 & 198 don't permit us to view the patch, but I assume he's from the same period. Once I complete the process, I'll post my hunch, or if I have a better match, I'll post that. I have viewed a photo of Frank Kenyon and don't believe it is he.
