Be aware that roughly half (maybe as many as two-thirds) of the AL-24 autograph cards were actually signed by Donnie Shell's wife. The autographs come in two different versions. The REAL autograph (as shown here) has a more triangular "D". The "D" in the second version is more "loopy" for lack of a better term. The "loopier" autographs were signed by Mrs. Shell. A quick Google image search will show that most authenticated Donnie Shell autographs have that triangular-shaped "D".
