I've actually owned this card for several years, but never looked at it closely enough to notice what Tim observed when he included a copy in the package he sent last week. From the angle shown in the photo, it looks as if Armando Benitez's right arm is missing from the elbow down. Obviously Armando was not actually an amputee, but that sort of thing would be a distinct psychological advantage for a pitcher.
I can remember playing with baseball cards as a toddler, but I actually started collecting them when I was ten. Now I'm an adult looking for an outlet to talk about my hobby without receiving blank stares in return. You can contact me thusly.
