1 & 2) Both obtained at a charity softball match in the Chicago, IL area. The major draws that weekend were NASCAR celebs, though other Chicago sports figures were in attendance. The promoters supplied the cards, so there's no clues on there (short of the signature). If it helps to read handwriting, the personalization on the first is for "Mike" (I hope).
3) Obtained just this past summer at a band signing after an Ides of March concert. Not Millas, Bergland, Borch or Peterik.
Thank you in advance!
